The naming of an angle is related to the line segments that create it. We'll also learn about the angle's vertex. Come on. Let's do this.

Geometry on Khan Academy: We are surrounded by space. And that space contains lots of things. And these things have shapes. In geometry we are concerned with the nature of these shapes, how we define them, and what they teach us about the world at large--from math to architecture to biology to astronomy (and everything in between). Learning geometry is about more than just taking your medicine ("It's good for you!"), it's at the core of everything that exists--including you. Having said all that, some of the specific topics we'll cover include angles, intersecting lines, right triangles, perimeter, area, volume, circles, triangles, quadrilaterals, analytic geometry, and geometric constructions. Wow. That's a lot. To summarize: it's difficult to imagine any area of math that is more widely used than geometry.
About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

Funny how this one video taught me more in 6 minutes than my geometry 1 class taught me in an entire week
@Harrison Szabo Ok Boomer
Mr Perish xDDDD
Lol
Mr Perish hmm

in my state you are allowed to credit by exam (basically skip) math courses by learning it by yourself and passing an exam to get your credits. these videos always help me out and they made me be able to take math two years above my grade level. (i used to be in an “on level” (one year below) math course which is crazy)
BRUHHHHH what state?
@@notimportant674 so we can go there
Which state is it? I should go there
Tell me
Bro. I need this be4 going into geometry. Im just searching up all the geometry videos i could find.
me too
Same I’m in algebra 1 and I’m trying to teach myself geometry before next year

How's life after high school dude 😂
I was so confused thanked for teaching me
We watch ur videos for math class....when my math teacher is there showing us ur videos instead of her teaching lol
Sophia panget mo
Lol
im trying to get ahead in geometry for when i start high school, so these videos are absolutely perfect for me. thanks mr khan! :D
So how was high school? 😂
lol
How did High school go?
How are u in high school I’m in fourth grade
@@lemur2151 They were born before u 🤦♂️
This is a great step in math for me im in the 4th grade
Gabriel Jones SAYYYYYYYYYY WHAAAAAAAAAAAAAAAAAAAAAAAAAAAT
+Gabriel Jones nc joke
+Queit Killer girl I'm also in 4th grade, my teacher said for us to find vids
Brah
study hard, little dude
U are so good at explaining this stuff. I wish u were my teacher. You are better than my teacher LOL!
so im here because im in second year i dont know what its there in america maybe 9th grade or something. But I got into a crappy math class because of my bad grades on exam so im really really trying now to learn geometry before we really get into it in school so ik the jist of whats going on. thankfully khan academy exists in my era.

This is helping me More than i thought
My test is in 9 min thank you appreciate it
Nice explanation
I understand it just in six mins
U r better than my sir .His topic takes weeks for me to understand
My brother who's in 9th grade taking calculus already. I envy him too much.
This is helpful for my class i don't want to fail so I am subscribed and I'm putting notifications on ofc
You explain angles very very well
Best geometry class I have ever had!
What’s the difference between angle names and angle measure? How do you know when to put the m in an angle? For ex:
Thanks so much for teaching me.
Thank You for the great videos. This will absolutely helps me in school.
you are a very good teacher
Great courses! Getting a geometry refresher course.
EASY Thanks Sal even though you are a bit confusing in ur other vids u explained i well so i subbed
Hi khan academy i recommend that you make the videos more interesting like math antics that would be a good update
Please pray to God
The only one
Math is a silly goose he will catch my fade
JazakAllah so much!💖
This really helped! I really helped! LOL
hi thanx
Nice teaching
nice !!!!
Nice
this is a great video thanks
Bruh my geometry class is 2 hours this is like less then 10 mins Lmao
I love math I hope I get a math teacher
These videos help so much! Thank you!
Got a test in 50 mins
thanks i think tis is so confused but no this is so easy thanks .
helps me alot
I got confused on what comes first a b or c do I need a dictionary
No u need a thesaurus
No need dictionary ... it was too easy it can be either b or it can be either c
we could call this ray, we could call, let me draw that a little bit straighter, we could call this ray AB, ray AB
Thank you for the clarity of angels it helps
*angles*
Since i was 2nd year high school at the age of 9, i remember this video learning advance geometry lesson. Sounds Classic.
CloudSky TV how the heck were you in high school at age 9
wthell u are...um...um...KIDDING
This is so helpful
Is there a video on finding angle between two lines in cartesian c.s.?
Nice job and keep it up
You are best i am your bigges fan
This is like the best
Yeah it is
ya my math teacher is also showing your videoes instead of teaching
Can you be a little bit louder
helped me in my geometry class! thx so much! SUBBED!!
Interesting
You are our savior Sal! Keep up the best work.
This is actually relatively easy it’s just my teacher sucks
What program do u use
10 years of advanced math down the drain this video is worth 1 year of studying
5:41 bac and cab
@Raidan Al-Arashi who you call bot
Good
my teacher sent this to me
these vids help me refreah allot for my exams
Helped me in school 😃
aden butt why is your name butt.?
I’m in 4th grade and I’m learning this lol
Thanks! I was confused
Math is easy. Its just the teachers. Smh. I could do alot better if these teachers would actually teach like Khan
Can we say angle ABC
But why are two dimensional angles relevant to 3D space ?
How are there 45,702 views and only 9 comments?
what if it doesn't say angle EHG or whatever and just says angle 1 or angle 2 and there's no visuals at all
Swag
How do u write with that? What did u do?

+Olivia Watts sorcery
if i only could download your brain data in to my brain.
when your parents make you watch this when your in elementary
but ur in elementary...
Don’t you learn this (partially maybe, Introduced?) in Elementary?
@@sonicvenom8292 i thought you were taught in middle school ? im in middle school and im just being taught all this stuff
Exactly my point.
The only reason i pass math
What🧐😕
The schools in my country use the wide hat instead of the angle symbol
E.g. (name): ∠xOy, ∠yOz, ∠xOz
Who asked?? Idiot.
I love angles;)
i dont care
lol

hello
profe lpm, ESTAN EN INGLES LOS VIDEOS, NO ENTIENDO UNA PORONGA
I think the people who disliked ur video are actually math haters 😂😂
Yeah lol 😆 🤣 😂 😅
Did they ever learn how to hold shift to make actual straight lines? Or does Khan Academy not have a keyboard in their setup? Ir maybe it's a style thing?
But yeah, in almost All competent drawing software you will wither have a line tool or the ability to hold shift and drag (mouse or stylus.) Most drawing programs with shape tools tend to make this the key bind for keeping dimensions for transforms.
I know for sure Smoothdraw has it, well not sure if it was a feature in 2011 though. Sadly no circle tool, it's a neat scribble pad though.

I agREE
no comment -_-"
i have also a ray in my pants
u mean A + RAY = ARRAY XD
The ray is 2 centimeters long, congruent to your dads

yes it does
Idk why but dream smp fans will understand this, why do u sound a lot like Ranboo
Nice
this is so useful
