not to offend my math teacher , but she never shows/explains us new subjects and gives homework and weekly quizes witch makes it really hard to raise/keep a high grade in her class, BUT ... Thanks to you , i always learn the subjects!!! , i went from a F to a D+, and my goals are to raise to a B , THANK YOU KHAN ACADEMY !!!!
As a 7th grader learning advanced math topics alone, it's not always easy to just read instructions in my textbook and fully understand the topic. But, thanks to Khan Academy, I can finally learn without any complications or confusion. Thank you so much!!!
honestly ive learned as much algebra as I have geometry in these videos..the whole idea of " prooving.....of "prooooooving" each answer( only you sal heads will get that joke.LOL) , he arms you with an insight thats hard to forget during its application. I really have much respect for his teaching ethic. Assume we know nothing( which is usually true) then show you everything but make it understandable..what a genius.!
I am sure if I was not so tired this would make more sense. I need a C+ in this class and I am struggling with a F. Guess I will be watching a lot more of your videos.
I have my gcse math exam at 27th and I understand a fair chunk of it. Watched the video twice, and I have a few questions: 6:41 if 2 Si equates 1 Beta, and if you take away the two, it equals zero, then why the hell is it half of Beta?! Or is it 0.5 x Beta? I see it recourring a multiple/factor (however you would call it), but shouldn't it be 2? Prominently at 14:02 shouldn't that formula be 2Si = 1Beta? This is messing with what I learnt from school, that a similar example of this, should 1Beta = 2Si, or 1Beta = Si x 2.
I dont get any of it ughughgughughughhgughguhugh!!!!!!!!!!!!!!!!!!!!!!!! I tried solving the questions yesterday and believe it or not , I spent 6 hours on this and till 12 pm , I rage quit!!!!!!!!!!!!!!!!!!!!
Nfs Payback you prob don’t get the background to it. Never give up, ik exactly what u mean, spent approx 2 days on nested fractions. Its ez now. Just put in the effort.
I think the whole idea is that is you make a triangle from the middle of the circle to two points of the circunference the angle of the triangle in the middle of the circle is gonna be twice of a triangle that take the same two point of the circunference but insted of parting from the middle parting from any place of the circunference. I'm sure nobody understood my explanation 😂

Angel G if not can
Angel G which not witch
Hahaha!!!!
did it raise to a B?
@@xaimpo That was a comment 8yrs ago bro idk what happend.

Oh, God, I never understood this at school... You make it look so easy!
Je suis française et je comprends mieux cette leçon que celle dans mon livre !! Merci
the only teacher on youtube which actually helps me pass exams and grading periods...thanks man
oneshot fan detected
If you haven't watched the video yet, pause it at 3:40 and try to solve the rest yourself! It's a fun puzzle
Thank you our teacher never even taught us this lmao... but its going to be on the test...
😂🔥
Excellent teaching !!!! Makes understanding so easy !

love your videos they help me fall asleep thanks
Lmao
A very good education platform...
time to pass my geometry test!
did you pass it ?
Lol 9 years later sheesh
@@Eng58612 years later…
You make it so clear. Thanks!
Thanks comrade, Many more students shall pass exams after quarantine thanks to you.
Great and slow explanation, after your explanation of the first case I got the other two.
Divine contribution for the students ❤❤❤❤❤❤
This man really out here drawing straighter lines with a mouse than i ever could with a ruler
Thank you so much for that clear demonstration
Very useful thank you, I didn't realise that geometry could be so interesting and informative
Omg thank you so much i have something due in a few hours and i havent even started
excellent very theoretical and straight to the poing
Life Worth Living yep, straight to the poing and pong
Thanks a lot! It was very helpful
this man is my childhood
Theta and si...very intriguing
8:00 How does the diameter prove that Si equals 1/2 Theta?
Brilliant . understand it now. Thanks .
I don’t get how si and theta are confusing..???
Si=x
Theta=y
i mean like your here aswel
I am sure if I was not so tired this would make more sense. I need a C+ in this class and I am struggling with a F. Guess I will be watching a lot more of your videos.
Amazing
Awesome explanation, geometry is beautiful!
can you please just use x and y the si and theta thing is really confusing
freddyyaniga studios true
@Just Me lol no
Thanks for the help.
I've never seen this before. Surprisingly, it never came up in any of the math classes after geometry, which I somehow missed.
interesting work.. love you salman .. Great man not ever born.
Really nice video ... our maths teacher uses terms which makes it hard for me to understand thanks to u the concept is clear thank u Khan Academy
Yes truly a good helpful one thanks
#khans academy
Ohhhhh this makes soooo much more senseeee
best best best best explanation keep it up
I really hate circles, thank you youtube!
thank you Khan
Thanks a lot!

I know you made this reply 5 years ago, but I had a stroke trying to understand this.
Love this proof
Very good at explaining
You have awesome handwriting
I would have liked some more real examples, like with numbers and solving for other angles
AWESOME! Best man alive :D
Th30Hacker Wait you r dead ;)
What about with quadrilaterals instead of triangles
this helped thnks
Very good....
I object sir............. fi 1 ias equal to fi 2 because they share the same chord........... kindly guide me.
Yes si 1 and si 2 are the same and angles and they have the same arc
Why do you hate X and Y?
Because My X wont get over me, she keeps saying she's "Sorry" but I blocked her eventually so its all gud.
Nice proof
2010 version of Sal ... op mic btw
great video
My book says same arc which is so confusing!Thanks so much for the subtended arc lmao.
go nice work sir
subtended...SUBTENDED...S-U-B-TENDED!!! LOL OKAY!!!!
Timothy Grant thats why I subbed and I didnt know why
the mystery
Genius
just kidding really well explained. your very articulate
good
About to have a math test in 40 minutes lol
i wanted to make a psi joke but i dePSIded not to
drevil37373 I was going to but you PSIched me out
💀I wanna make math jokes
I still dont get it
Sullivan Nix noooooooo
Wait isn't that angle at 5:03 supposed to be a linear angle too?
what app do you use
What programme do you use when you're drawing?
it's their own software
thumbs up for hd
should give us numbers with the examples
has any1 told y that u have awesome handwriting?
Am 14 year old now 😂
sounds like frank zappa teaching geometry :)
What if there is another central angle? I don't know what to do :/ there are 2 central angles and 1 inscribed angle in my problem
i know im 5 years late but lol idk
I am confusion???¿¿¿?¿
Sal. Even though this video help, it would been better if you state the theroem and postulate.
Allen Deng no theorem fam just equations
cool bro
i wish there's another way to explain this.
Wait, what?!
This is why I didn't want honors geometry...
I wanted last proof
Oh yeah sigma😁😁😁🤣🤣🤣😂😂
X and y is confusing
*Not to scale
His voice reminds me of Samuel L Jackson... O.O
ima pretend i understood
WHO'S WATCHING THIS VIDEO IN 2008??????!!!!!!!!!!!!
+Joseph Green "Uploaded on Mar 18, 2010" its 2019 dammit
+fangirlninja lol
I’m just trying to complete an 8 question quiz😃 and i’m tryna to not fail it yk…i’m too stupid for this and tired lmao.
im the newest comment here
yeah this is way too confusing tbh
Why do I still not understand…
THIRD!
oh god, this is 14 minutes
Eileen Taylor oh god, a complainer
Smarrtt
Mahol
Me did the whole video: si.... theta.... wait how do your pronounce these... r.I.p x and y
I dont get any of it ughughgughughughhgughguhugh!!!!!!!!!!!!!!!!!!!!!!!! I tried solving the questions yesterday and believe it or not , I spent 6 hours on this and till 12 pm , I rage quit!!!!!!!!!!!!!!!!!!!!

Plz stop saying si or thetha or whatever it is it’s confusing
bro MLG
How?
