love how you started with easy questions and then gradually demonstrated harder questions
Thanks! Its all about baby steps.
so true
today is not yesterday That makes my day! 😊
@@MrHelpfulNotHurtful my math teacher only does easy equations then in the test is the stuff we never learned really
@@frozone2366 I’m sorry to hear that. You are smart to go on TH-cam and study other examples to be better prepared. Improvise, adapt, overcome! 😎
Took my teacher the whole 2 hours to just what you taught in the 1st 5 minutes! Thanks man!!!!
You are super welcome. :-)
honestly! best techer
In 5 years this is the first video that i am giving a like to on TH-cam.Would recommend to every geometry student.
Already 5 yrs here and my teacher recommended it
this taught me a whole weeks lesson in just 30 minutes
BOOM
This video was incredible. I sat through a 2 hr class session and was confused. After reviewing this video I took a class quiz and got 100! Thank you so much. Will definitely share your videos with my study group.
Yay!! It makes me very glad that you are finding my videos to be helpful. 😊
Omg thank you so much!
My teacher confused the heck out of me and you made it so simple. I got to finish my hw thanks to you. :)
You are very welcome. It makes me very happy when I can help somebody out. :-)
omg, ARMY
sarah coyle
Lol hey just here trying to pass my class for the boys
that's funny. HIXTAPE DROPPED, sorry, i have been waiting for it for like 3 years. oh wait, more like since i was in middle school.
What is a triangle that has 10 inches long
omg because of you i am going to pass that test thank you so much
jorge bocarando
Yes! That's what I'm talking about. I got your back. 😎
Literally a life saver, man. I understood this within minutes and now my hw is easy peasy. Not to mention, you made this lecture fun, which is freakin cool. Thank you so much, i’ll definitely look for this channel when i need help! 🙌🏽🙂
Yay!! I’m so glad! 😊
"How do I say this without hurting your feelings?" lol I've actually learned more from this video than I've learned in one geometry class, extremely helpful, thank you!
+Mary Burkett Yay! You are welcome. You scared me for a second there. :-)
My teacher spent a whole class period trying to explain us this and I still had no idea what to do. But watched one TH-cam video and I understand now. Thank you for this video, you really saved me.
I'm so glad I could help. :-)
You are super welcome! :-)
Thanks so much now I won't fail my geometry test
Out of all of the tutorials on this subject, yours is the most understandable, and helpful. I hope I'll pass my test--thanks, in advance.
Good luck!
Thank you so much , I've been struggling with these for more than a year and in less than 40 minutes you've cleared everything up for me !
+BiG -T Yay! I am so glad I could help. :-)
YOU HAD TO BE BORN. THANK YOU !
zetreen Henriques
That's so awesome. I feel like my whole life was just validated. It's so nice to feel appreciated. 😊
Your video helped me understand this on a whole new level. Thanks for your patience in making these and showing multiple examples. Helped tons!
Michelle Montoya You are very welcome. I got your back! 😎
Thank you SO MUCH for this video!! I watched about seven other videos on this topic and None of them explained what I needed, and you explained it within the first 3 minutes perfectly! This was incredibly Helpful! I'm so Grateful! I don't have to stress myself out anymore:)
Yay!! So glad I could help. :-)
you are soooooooo much better at explaining than my actual teacher thank you so much
M&B I’m really glad I could help. 😊
Thank you so much for explaining how to find the other legs when you have a hypotenuse with a radical(in the 30-60-90 triangle). Seriously you just simplified in a way that actually makes sense! Jeez everyone else is making it so convoluted :/
thank you!!
You are very welcome. Glad I could help! :-)
Amazing !!! Amazing !!!.Amazing !!! Amazing !!!.Amazing !!! Amazing !!!.Amazing !!! Amazing !!!. If we have teachers like him, all students would get 100%
Wow. Thank you so much! I'm so glad I could help. :-)
wow, i have been watching so many videos these past few days trying to understand this unit, and every one left me still confused. thank you so much for explaining it the way you did, and gradually going into it!! i now understand it so much better
Yay! I got your back! 😎
my goodness! the way you teach is much more understandable, thank my teacher's
Thank you. My son was so frustrated and your video made homework much easer.
I’m so glad I could help. I appreciate your feedback. 😊
thank you so very much I did not understand this in class and we talked about it for a day and I'm in pre ap so we don't ask much questions but after seeing this I feel confident for my test .! thanks.!!!
+dulcechick You are super welcome! Glad I could help.
you just explained this better than teachers who have been teaching for 20+ years
Michael Ogbonna Awesome! Thanks for the positive feedback. 😎
thanks Mr. Helpful. I had a very difficult time understanding these triangles before watching this video
Yay!! So glad I could help ! 😎
Finally, a teacher who understands that, you won't get work from students till you get into their shoes. What i mean is you weren't to lazy to use more advanced questions intead of those boring, and uneducational one digit questions. YOU JUST KILLED TWO BIRDS, WITH ONEEE STONE. THANKYOU! Please keep it up, because not all teachers do, for its like trying to cook your own food: you have to prepare it, clean it, figureout you craving, then start to work you way out with time, which you constantly have to work with.
Thank you so much for the awesome feedback. I don't think I've ever had such a detailed and poetic comment before! :-)
@@MrHelpfulNotHurtful thankyou, i get compliments all the time, but this is a bonus video, i even subbed, or so i think, but if not, im doing that right now 😊👌
@@MrHelpfulNotHurtful yeah, for some reason i forgot, but i just go you another one. Your welcome, though this may not influence you, unless this is one of your careers.
It’s been a few years since I took it in high school. Currently relearning this in college & I needed a refresher. I couldn’t figure out how I got in high school, but you made it sooo easy! Thank you!
Maria Vicente Yay! I’m so glad I could help! 😊
i wish my teacher taught like you! thanks!!
You are super welcome! :-)
Thank you! 👏👏
Edit: I can finally breathe now
This channel needs more subscribers tbh. It’s everything students need.
Yay! So glad I could help.
What an awesome amount of information there is in this video. Thank you Mr. Helpful
I appreciate the feedback. 😊
This is from a geometry class taught in 10th grade.
Thank u so much you helped me sooo much I'm so confident for this test now
I fucking love u, why can't all teachers explain it like this. Thank u so much dude, I appreciate it. Keep doing ur thing my g
You made my day, bro! :-)
I did learn from my boss that a 3,4,5 triangle is old farmers triangle, ccause farmers didn't have calculators ,just measuring tape so they would pull 30' over set point then intersect that point with one extending from other point 40'with 50' and they could build their fence seprating their property at a 90^ from the road.
That's awesome real world use of Pythagorean triples. I will definitely tell my students. Thanks! :-)
thank you!!! you made special triangles so much easier for me since i forgot all about this last year taking geometry. this will definitely help me during my ACT test in two weeks!!
+Somali asf You are welcome. Good luck!!
now that corona virus popped up you're more useful than ever! i understand much more when watching ur vids than when our teacher just sends us a paper on classroom.
SavageBRO Yay! I’m so glad I could help. You are right, a good video is even more important under these quarantine conditions. I don’t know how I would teach without them.
This is extremely helpful thank you, when my teacher taught us this we went over some easy questions but after a while we were given a packet which had questions that we've never seen before that he didnt go over on how to solve, thank you
I had the same problem
This was SOOOOOO help for my test today you dont know how ready i am now to be honest you taught this better then my teacher im so grateful for this video
Yay! Glad I could help. :-)
I am taking my Praxis Core test this summer. Thank you so much for these helpful math videos! You explain the concepts very well!
You know I got your back, Girl! Good luck.
Thank you. My teach was sick today and this lesson was our homework and I understood it all thanks to you.
That's awesome! I'm glad I could be your substitute teacher. :-)
Never thought I would subscribe to a math channel...Glad I did. Thank you.
Peter Cipriano
Wow. That's awesome. Glad you are finding this stuff helpful. 😊
Video taught me more than what my teacher did the past week
Yay! So glad I could help.
I woke up from a nap with this on, For what I'm doing I don't need this, but I want it if you know what I mean. My High School Teachers didn't care if the students learned or not so I lost interest. Making my way without the fundamentals of Trig really held me back. Now thanks to you (I've got those) and I'll be back later to learn this and more, just for extra credit. 👍😊
Roy Smith That is so great to hear! Are you going into algebra 2 this year. I have a whole set of videos for that course. Check out my channel when you get a chance. 😊
I was seriously struggling with this, this is the first video I could actually understand thank you so much 😭
Yay! I’m so glad I could help out. 😊
wow this was by far the best explanation I've seen and I'm 25...thanks so much for the post!
You are very welcome, My Friend.
learned more from this video than I did in the last week in a half
Yay! I'm glad I could help. :-)

Jasmine 😊
Helpful video. This would work well with a flipped classroom. Thanks
Thanks! I do use these videos to flip my classroom quite a bit. :-)
Don't forget the 3, 4, 5 right triangle -very useful in laying out large right triangles - even for building construction and property layout. Practical knowledge of trigonometry is quite useful in solution of any triangle, in addition to right triangles.
Walter Brown Excellent point. Thank you. 😊
thank you so much, i was struggling with this so much and you explained it perfectly
You are super welcome!
Thanks a lot MrHelpfulNotHurtful!!!! This helped a lot and I will definitely be more confident on my geometry test tommorow!!! Thanks again!!
THANK U!i wish u were my teacher....
+Yadi Adil (Kurdistanakam) Yay! Thank you. Best compliment ever. :-)
Thaannksss !! 4 classes not understanding from the teacher and by 10 minutes I clearly understood everything ❤
Yay!!!! I’m so glad I could help. 😊
I've just discovered that this channel has a wealth of maths videos, people go and check them out.
Stay safe ✌😷
Red Angry Bird Thanks! 😎
OMG! Thanks for this video! like i am blessed!!!! You have cleared a 2 hour math period on this in like half the time!
Aneesa Yaqoob
You are super welcome! 😎
Thank you for helping me and my son!!! We were lost and the class notes would not help. Thank you, Thank you, Thank you!!!
You are very very welcome. :-)
thank you so much!! i understand this WAY better than how my teacher thought it, & I have a quiz tmr ! Wish me luck.
melindaxo
You are very welcome. Good luck! 😎
This is going to help me pass my trig test tomorrow!Thanks!
Yay! Good luck. :-)
Impressive! You made this so much easier than others have.
Thanks! So glad I could help. :-)
i looked through many videos explaining these but this video really helped me understood. thank you so much!
Yay. I'm so happy I could help you. :-)
Who gave this a thumbs down???its great
Thanks!!!
Thank you so so much I have a Geometry test next week and I haven't been getting it until I've watched your video!!
You are super welcome!
Thanks. Really great video btw. Loved how you gave us many demonstrations. 😁🤓
Thanks so much dude MY TEST DEPENDED ON THIS!!!!
I've got your back! :-)
Was confused with this during class (For like, a WEEK) in school but this helped me finally understand! 😎And this took less then 40 min! Thank you! :D
Yay! I'm glad I could help. :-)
You're the best. make it so easy to understand. Thank you very much. continue your good worrks
Thanks! Glad I could help. :-)
I know I’m super late but thanks man 🙏 your a life saver
You are welcome. So glad I could help out. :-)
Finaallllllyy found a video that makes sense
Yay! :-)
First of all, thank you so much for the video. You really made it sound so easy. One question that comes to mind is what if the triangle has angles are not 45 45 90 or 30 60 90. How would you find the lengths of x, y, and the hypotenuse ?
That's when you have to use sine, cosine and tangent. Here's a video:

Honestly, thank you so much. I could've never gotten this.
You are quite welcome. So glad I could help! :-)
Great Work complete explanation in details for students .
Thanks! I really appreciate the feedback. :-)
3 mins in and i understood the entire lesson omg ty

So glad I could help, my friend. I got your back. 😎
this was very helpful at 2 am in the morning :)
So glad I could help. 😊
Get some sleep !
Thank you!!! This video helped a whole lot!!!! TERRIFIC JOB!!!!
+jennifer jacobs Yay! Thank you back. I'm glad I could help. :-)
Omayghad!!! This is the most helpful tutorial I've watch for my exam tomorrow 😂😂😂
Yay!!!
I might be late on this question but what do you do if your 45,45-degree triangle has a hypotenuse of 9 or something
Let's call the hypotenuse h and let's call the leg x. The hypotenuse always equals the leg times radical 2. So we have the equation h=x (radical 2). If the hypotenuse is 9, the equation becomes 9 = x (radical 2). To solve for x you divide both sides by radical 2. You get x = 9/(radical 2).
What if you have a 2 radical 3 for the hypotenuse? Would that make the short leg 1 radical 3 or just radical 3 and the long leg 3?
Yes! That's exactly right. :-)
thank you so much!!!! you teach me better than my awful math teacher!!!
You are very welcome!
How did you get 3 radical 3 in the calculator? I got 5.196 : (
but besides that this video is great! It helped me a lot :)))
+namjwwn I used a TI-30 XS Multiview which simplifies radicals for you. You should get one. They are $15 on Amazon. Or for $21 you can upgrade to the TI-36X Pro which also solves systems of equations.
+namjwwn I am assuming you understand that 3 radical 3 is numerically equivalent to 5.196...
Can you explain how things would work if the 60 degree angle was at the top while 30 at bottom? I heard it is different that way and you have to multiply the hypotenuse by radical 3.
Rotating the triangle so the 60 is at the top changes nothing. All the same rules apply. At 11:43 (and other places in this video) there is an example with the 60 at the top. I can find you more examples if you need them.
Thanks for the reply but I meant how what if 60 was switched with 30 in that example. Like if you completely switch the angles around not rotate. I watched a video from yaymath about it and thought it had some sort of change to the formula.
I learned our whole lesson in your 1 vedio where it took my teacher almost three weeks to teach the whole class
Naomi C.
It's like you have two teachers now. 😎
the goat as always
You just made my day. 😊
Thank you man!! i hope is pass on my test today!!! very helpful
You are very welcome. Good luck! Let me know how it goes. :-)
Best explanation ever 💯
Yay! I really appreciate your feedback. 😊
thank you so much! this cleared up my confusion and im so relieved!
Sedra Muhtar Yay! I’ve got your back! 😊
when yur a couple minutes through and feel accomplished cause u know how to do it. I like how he kept referencing the model of 24 24 90 and 30 60 90. :)
Im a freshman in my honors geometry class and i was having a mental break down on this then i watched the video and got a 99 on my test
Woo hoo!!! That makes my day. 😎
Great video. Awesome teacher, thanks man.
I really appreciate that!
Thank you!! You are a great teacher.
You made my day! Glad I could help. :-)
you got another subscriber sir,thank you so much.
Bambi Luong Yay!! Welcome to the family. 😊
thank you so much, now I could answer my homework
You are very welcome. :-)
I could now follow the flow of our lesson.I also shared what I learned here with my best friend.Thank you so much, hope you do more videos like this😄
you're really a good teacher man, again thanks a lot
You are super welcome. So glad I could help! :-)
Here is a playlist you might find helpful:
th-cam.com/play/PLUq8yM4tK_aWwFafJz_JOyR7PYazY49cG.html
When the long side is 4 and root of three, the short side is 2 and root of three, what would be the length of hypoteneuse.
I disagree with the premise of your question. If the long leg is 4 root 3, then the short leg is 4. The hypotenuse is always double the short leg, so if the short leg is 4, then the hypotenuse would be 8.
For a 45-45 what if the hypotenuse is just 7? How do I find out what the other sides are
This video will show you why the answer is 7/root2: th-cam.com/video/pR_J5feDcEM/w-d-xo.html
I agree. Can you draw a triangle of long side 17 and adjacent side is root of 85.
The triangle you describe would not be a 30-60-90 triangle. You would find the missing side using the Pythagorean Theorem: a squared + b squared = c squared.

this is more understandable than my teacher's lesson 👍
I'm here for you. :-)
Thank you you are a lifesaver
You are very welcome. So glad I could help. 😊
