i don’t understand my online class so i’m here.
Hahah same but I’m in school not online but my teacher don’t explain good
I have a test tomorrow and I know nothing I don؛t even know what’s geometry or ANYTHING 😀👍🏽
How did it go?

@@UrMom-jf2hk thery failed
Literally I’m about to fail and I already have a d in that class bc I don’t understand it 😅
Same this is only the second thing ive studied 🥲
Thank you for the visuals, I spent weeks trying to understand rotation, looking at other teachers'videos, this is so much easier to understand.
Noice
I saw u at another vid saying the same thing
@@dippin_c00ki32 Noice
who else looked at the comments to see if ur friend commented for online learning
Hello
Antonio Yax u gotta be kidding me, lol 😂 u found me
Yep I always look at the comments in every video
LOL
this taught me more than my damn teacher
your teacher sucks
my teacher gives me rotations without even giving my protractor back
same lMAO

Thank you!! I go to a very intense school and completely missed the first day, so I couldn't keep up with my classmates in this. You just saved my butt from a test today :))
god bless your soul for this. Guys im not failing geometry anymore C:
broooo fuck offf howwwww i got a test tomorrow and i don’t understand shit
@@yangyang857 HELLLPP I DONT EITHER I HAVE A TEST THURSDAY
Thats cool but uhh who asked?
@@AaAa-ve5vy Worth a try. Be more respectful next time bud
I am soooo appreciative of these AMAZING videos you provide! I am forever grateful! As a high school geometry teacher, these videos are a great way to introduce a lesson to my students in order to pique their curiosity and interest. Thank you for the simple yet elaborate visuals and perfect speed of speech so that all learners can understand!
Honestly it might be a difficult for (some) kids with adhd. Their brains moves so quickly that math videos can be almost unbearably slow. However 2 possible solutions can be to use subtitles, or if that doesn't work out let them watch it on their own at a different speed. (If you can)
I've played this over 3 times and yet I've been distracted doing something else😭🙂 and I still need to understand this for my online class..... if I'm being honest I miss face to face class now🖐😭 cause it's been one whole year since I've been dunce 🥲
You don't know how much this helped me!!! I was struggling so much with rotation but this video helped me understand it way easier !!
Video is very well done. The instructor does an excellent job of making rotations easy to understand! MUCH better than the geometry books that I have.
I am 100% subbing. My teacher has been teaching me this for about 2 or 3 weeks now and I still did not understand but then I found this and now i understand ike wow!! Even now am still shocked that I could understand this concept in 11 minutes. Keep up the good work 👏👏👏👏
teachers at school make this shit sound harder than what it actually is. thank you for this!
when you get a notification on your phone for a second check it out the whole lesson is done
This is more than helpful! I bet I'll ace the test tomorrow thanks to u!
How did the test go?
Your asking her after four freaking years 😂😂
@@abdullaahmed4444 Ratio 🥶💯
How did your test go!
how did the test go
This was actually pretty informative, dare I say I think I learned something!
i have a math test tmr and rotations was something I was so confused on thanks so much
this was so amazing good for lesson plans
You explain better than my online teacher and know I get it thanks man !
Great illustrations and animations to highlight the concept of plane movements in transformations!
This was extremely helpful to understand rotations more clearly!
Superb presentation .
Excellent Teaching.
Thanks Sir.
Thank you so much!! I didnt understand it and i had a homework assignment due today. Now I finally get it. Thanks a lot!!!
You get a subscriber for explaining something my teacher couldn't do well!
How many r watching this the night before finals
who has finals an this?
BeddaAsCheda Final exams are school
im teaching myself the whole semster of math the night before finals
This helped me SO much! I couldn't find any videos that explained the formulas so this saved me a ton of time looking for them. Thank you!!
I subscribed to your channellol
Thank you so much. I am using your video to do a lesson for my students. the Engagy lessons are so confusing to my 8th grade kids. this is so helpful. Thank you
Who else is in school?
SavagePatchBoy me
Quarantine
Mee
Mya. Still quarantined :p
Me in math
This was extremely helpful in making rotations understood!
Thank you, this was super helpful!
Is it important to memorize the algebraic expressions for the different angles?
when you were talking about the rotation rules what if the 3 was a negative 3 would it still be the same or would you change it
just had half of a test yesterday, screwed up the rotation part. you just saved me from failing the second half today.
Thank you for this video. Your visuals helped my daughter complete her homework!
When you’re here cause you have a final next week
How did it go?
This is incredibly well done! I am finally understanding rotations....thank you!! FYI your other videos are well done too...props!
Thank you so much this helped me from being behind in homework!
0:46 IT TOOK ME A WHILE TO REALIZE, HE WAS NOT SPEAKING BACKWARDS
MOOM WOOMY .uoy ot foO
❤❤❤❤I now understand I am going to write checkpoint with rotation and you helped me understand.I have been taught over and over again but I still don’t understand. Even everyone in my family doesn’t understand. Thanks a lot ❤❤😊😊😊😊
when you watch this in class, then come back for more as a study guide 😂😬 #ImLame
+briana claiborne Aw yeah! Thanks for the support, Briana! I hope that you can subscribe to our channel and continue learning with us! -Anthony :)
Dude im watching it in math class right now
me irl
This is the damn best virtual tutor
Thanks you helped me a lot i love yall so much
@MashupMath what app or program do you use to show the shape rotating on the coordinate plane?
what are you using for the animations here is it just google slides or how do you rotate the quadrants? anyone knows? thanks
Helped me a lot thanks 🙏
love your lessons wow
Can you tell me where to find the free worksheets that go along with the videos?
+Geneva Teal There is a link in the video description! :)
This helped me understand better in was a little confused😅but thanks for the lesson😊😊
The summer school site they're using doesn't let me speed up the videos and it's killing the few braincells I have left.
Great video, makes it very clear how to find the points. But, I can't wrap my head around WHY, clockwise is negative and anticlockwise is positive??
THANK YOU SO MUCH I GET IT NOW! I had to come here because i didn’t pay attention in online school and i have a quiz tomorrow
great explanation!
Thanks you! I am having a hard time at school with depression, this should help me in math and soon my depression.
Great visuals! And if a person doesn't want to solve these mathematically, the visuals allow for some great work-arounds.
i got a test today hope this will save me today
Tysm man, your the best💪💪
U saved my life man thank u
Excellent........ excellent.......... excellent presentation
I can not understand in the example the negative 180 is (-5,8) but in the rule of the negative 180 the x and y (-x,-y) were negative . Can someone help me ?
i’m here cuz i’m failing traumatically 😩🤚🏼
This video is very helpful thank you.
no loser
@A Box Of Chocolates he is a friend at school
Haha loser
Just watched this video when I was in class. Using it to study again.LOL
Great vedio to build concept
Positive rotation is CCW, negative is CW
thanks! I’m making my own studyguide for my exam tomorrow so this helped a lot
Thanks for supporting
You've just saved me from me math test
does this only work about the origin??
This helped a lot
THANKS SO MUCHH!!!!!!!!
I need help! The 90 degree cw rotation rule doesn't work for (3,-2) I thought it would be (2,-3) but really the answer is (-2,-3). Why is the rule different???
for R-90, the Y coordinate doesnt change it’s sign so -2 would stay -2, not become positive 2
I was falling asleep in math class that’s at 8:40am and I missed the whole lesson 😔
I'm sure glad I watched this video I was so confused about rotation!
yeah same
Holy shit, im behind by 4 hours in my geometry class because of rotations and thanks to your vid it just clicked. Thank you
thank you bro
I’m so confused I can’t handle this ima fail😩😩
SAME 😫
anna go to sleep
THANK YOU!!!
rotations preserve orientation. Reflections change orientation
Thanks so much dude
Thank you
Who else came here because their teacher was too lazy to make a lesson video for online learning?
me:)
topics are good for all math teachers even
مشكور مافهمت بس فهمت 🧍🏻♀️
How did the rotation get lost?
Tell me your teachers suck at teaching online without telling me they do. I'LL START! I'm watching this video.
Help please!! I got confused on some topics..
Do Points have direction??
no
I'm only late 2 years lol
i dont really use common core math but this was still extremely helpful
Thanks for the comment! I'm so glad that you enjoyed the lesson. I hope that you can give the video a thumbs up, subscribe to our channel, and continue learning math with us! -Anthony :)
cool
omg it's so good

So, I was absent, and my teacher usually posts the paper we took notes with and the video of him explaining it. Mf put the paper, but not the video, so I’ve got a blank notes paper, and a quiz in 2 days... fucking end me...
Edit: didn’t do too well... we went over the answers in class today so we have something to study, and I tried so hard not to laugh at how off my answers were. But thanks to this video, I at least got a C.
Good job, you didn’t fail and that’s good enough
I came back from school and used this to study! My math teacher showed this to us
I think that's cool!
7:48
(just a time stamp for myself)
This is why I understand rotation
I get it but I dont know how to do it on a piece of paper, (how to rotate it)
Hi MashUp Math. I am quite confused on a coupe of things. First of all, Why is it that when you show the rotation rules for the CCW, P' (-y,x) P' (-x,-y) and P' (y, -x)? I thought that you write down plane coordinates with the x-axis first for every coordinate. Why does it change for rotation (or is this a simple mistake)? The second thing is, I am also confused as to why the coordinates almost "flip" in the rotation CW rules. What I mean by this is, for the R-90, it says P'(y,-x) but when you add the numbers, it clearly states that for R-90 it is P'(-8,-5). Then when you added the numbers, the R-180 said P'(-5,8). Why did it switch? Please help me with this confusion. I am currently studying this during the summer in order to move up a grade in math. I would appreciate it if you answered before school starts. Thanks! great vid btw :)
I am 6 years late, but the reason the x and y coordinates are flipped is because the coordinates, say (2,3), are switched and become negative for 180 degree rotation. This means that it will become (-3,-2). You are correct about the x coordinate going first, the value of the x coordinate is what is changing. I hope that makes sense, and I apologize for being 6 years late.
