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.
For free. For everyone. Forever. #YouCanLearnAnything

we out here in 2020 still confused on basic calculus
Gravyyy hahahahha
Bruh I'm doing this in online school for 9th grade
Synvc different lessons carry on with math
@@hunterpetrovia9454 me too
me lol
The, Khan-cept of triangles
Hello There.
This implies that Obi-Wan has canonically taken geometry and struggled with it
NICE
Currently sobbing from this horrendous dad joke
Haha
When you realize that this is a video of the year you are born.
It just kinda hits different !
Thank you Sal , I hope the next generation will also take the goods from you and Khan academy!
Same lol
Yea same
same jajaja
This video is literally older than me 💀
@@delev11 Same. By an entire dang year.
WOAH TRI-ANGLES. I get it.... Sometimes it takes me a while to get these things.
XD
Same
lol
Lol you just made me realize. MIND-BLOW
Mind blown bro
you explain everything so much easier than my teachers. thanks so much
hi
casey where you at now
@@ballerspro8310where u at bro
It’s 2024 💀
"lets say.. we know.. i don't know.."
Omg thank you so much. I just started college yesterday and totally forgot how to do this!
Did you graduate yet?
My mother passed this curse of not being able to do geometry on to me
Same
Literally the only thing I struggle with in math
“Triagles..heh heh”
-Khan academy guy 🤣
That was a perfect flashback in to my school years. Thanks alot.
240p feelsgoodman

I looked this up to prepare for a Calculus test XD. I find it hilarious that the hardest part of calculus is all the basic multiplying and rules we've already been doing our whole lives.
Gigadrax I'm trying to understand some deformation of a shape in an engineering course
Me whos learning this in geometry
@@helix4267 same
dude ur the fking AWESOMEST maths teacher ever i love u
It’s hard to believe this but you wrote this comment when I was 4 years old
@@OSEAN_AIR_DEFENSE_FORCE yes when I am six year old
@@palarpachidvilas7477 lol
I forgot my book at home, and I had a test the next day! I couldn't study.... but then Khanacademy saved me! Thanks Khanacademy!
How was your test?
My sub barley explained this to my class so some of us barley knew the material. but we watch your videos 24/7
I love spending Friday evenings watching some guy talk about triangles for 10 minutes... I’m exactly where I wanna be rn
This was put up on TH-cam on my birthday!!!!!!!!
happy birthday for yesterday then... Im in australia so maybe not yesterday for u
Bad Username Shreyas Vids no one cares
Elijah Haridas nobody cares about your comment either
NoLimitChris ya thx
Bad Username thxx
Thank you so much! I am in 6TH Grade HI-CAP Math class, and we are going to take a test on this. OMG though, thank you SO much! I would have gotten an F if not for you... you earned my sub
AliKat Gaming I KNOW RIGHT! IM A 7TH GRADER IN MATH PRE AP AND OMG IT HELPED THANK YOU KHAN ACADEMY lol

Can't wait to come back here when I'm in college where I forget basic geometry 🥰
Thank you for this video. My teacher has an accent so it’s hard to learn from her sometimes
Thank you soo much!
thank you so much.
slept through my zoom call. now i’m here. thanks for the lesson!
wow mean thank you so much for this video! you are more than great!

@gyarin40 Its used alot in programming and real life application especially in space. You just have to search to find what its used in :). Plus its interesting concepts.
Why are the comments up here this is not floor gang
your voice makes want to hug somebody. lol
lol
This really helped! Thank You so much! :)
Ahem.
I know haha, I use Khan Academy too! :) Aishwarya Singh
I swear, this man is the messiah of math!
Hello :) A Im also theacher in maths , sorry for my bad english - but it is not aloud to write x and y for sides and angels in the first part :))) but is nice video, thanks!
10 years late but yes, it is allowed, why would it not be?
world best teacher...ever
i love learning in 3fps
Thanks sir
thank you soo much for this it helps me too...but the sound is quite less 😂😂😂 so kinda say loud ...but its really good ...I got soo much help by it 😃

This video was posted before I was born. It’s still useful.
12 years!😲
helped a lot thanks
thanks a lot helped me answer a few questions
Gud 1 but how do v find angles from similar triangles
It's been 9 years, did you ever find an answer?
Thanks that help me get a good mark in my GCSE
I never know you can get an exam in geese
How tf did u have this in ur gcse i have it in year 9
2019
Original
That "Hello" legit gives me goosebumps lmao
i swear this is my math teacher
thank you i missed that lesson in class because i was sick and that made my homework make sense
Thank you. You have helped me for my test tomorrow aka GA MileStones
I took that too
I LOVE KHAN ACADEMY
Thank you so much for this.
Thanks

Triagles
i came here cuz i JUST LIKE TRIANGLES
Thanks help
So basically if the angles of 2 shapes are the same on the corresponding side.Its similar Right?Thats the one thing?! please answer!!
Yes, if all the internal angles of two shapes are the same then they are similar. If the lengths of the sides are also the same, then they are congruent.
y no graphic ate bottom?
Khan Academy to the rescue.
Thx
Nice 240p quality you Rockin there
jk no hate thx helped a lot
**writes triagles**
him: no wait it’s triangles not triagles
I still don’t understand
same bro
Same here
How we choose two triangle I. e in which order from given figure
Love it
helpful
great sid
Thank you kind Indian man 🙏
man this was really helpful =]
Anyone watching this in 2021?
i am watching in 2019
i am watching in 2020

right
good ol' sal Khan
In the very first example could you also say the ratio: 7/5 = x/2
are videos from 2006 really helping
I am just 2 months older than this video.........
@xxhyperchocolate did you ever get your Samsung galaxy three years ago?
Are you new? You seem to be fumbling with words and it's a little confusing. I recommend learning the topic and using this for revision.
The WolfHowlxs He made this video is 2007. Watch one his new videos. Pure educational value!
the words r not tat clear but helpful
2019? 😂😭
2020?

@@biscuit6116 2021????
nah 2021
does this apply to other shapes as well?????
Yup
you made this before I was born lol
Confused
I am not sure if the choice of numbers is the best possible for a first lesson :)
how spell similar?
Similar
@@chogiwwwaa9322 10 years late lol I think they found out how to spell it…. Dang the days before Covid all I can think about
what grade yall in
I only have one more try on my test and this isn’t helping I have to look at the numbers in the angles and know if they are similar
People after 14 years of video 👇👇sry 12 maybe😁😁😁
THE ONE WHO IS SEEING THIS VIDEO ANYONE THERE I AM 😁
Geez, this video was recorded the year I was born!
hello from the other side
This is funny and cute!
:)
WHY do you say sides are corresponding when they are opposite the same angle instead of simply saying because they ARE PART of the same,angle..meaning it is the side or edge of the same,angle as in the other triangle just a different length..much more straightforward..just curious..
i dont understand the ratio stuff, what video has the ratio stuff in it?
My math tutor was supposed to come to my house today, but she canceled last minute. My test is tomorrow so yup life is GREAT!
