Introduction to the Pythagorean Theorem

Missed the previous lesson?

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.

My teacher took 4 months to teach us this, you summed it up in less then 6½ minutes. =_=

Math is sometimes painful, but when you understand it, Math seems like MAGIC...

So much better than my geometry teacher. THANK YOU. <3

I’d bet this man never thought his video would be relevant in 2020 it’s sad I’m learning from something ten years ago than I’m learning from “Online school”

[shannonmarbut]

I came for the maths, and stayed for the impressive handwriting.

i dont start to slowly cry anymore when i open my math text book

[Miiilked]

Thumbs up if you came here because you have a test tomorrow

[rannemalshehri]

50 minutes wasted every single day and when I watch this 10 minute video I understand every single thing
Wow just.... 😶 Wow

[OGBlueWarrior]

My math class is gonna start learning this on Tuesday (tomorrow), so I decided to learn what this Theorem is. The second example blew my mind! Whoever is reading this, I hope you understand this just as much as i do and I wish you passing grades!

i was stressing over this for hours while I could just open yt oof

[ann-cakes]

I doubt anyone from khan academy will ever see this but, you guys have changed peoples lives and will for a long time and I really respect that.

(teacher teaching PYTHAGOREAN THEOREM)

Me when learning this : WHAT!! IT'S SO BASIC!!

Me when during test : did our teacher teach this to us? I don't know this!!

[officialburrito]

Math class in schools should be relegated to a guiding teacher who introduces subject matters and helps us when we have questions. However the bulk of the instruction should come from clear and concise videos like this one which teach concepts in the most effective and polished way possible.

I learned more from this then the entire school year thank you kind sir

[arshali]

Man be my maths teacher plzzz!! My teacher of maths goes like 1 chapter 1 day and i am in 7 grade....he told me this theorem in one your videos man !!!!

[berhanarslan]

DAMN!! THIS GUY IS GOOD WOTH MOUSE WRITING!!

[dsgjydj]

I couldn't believe that I'm bored enough to watch tons of math videos as entertainment


*quarantine days*

[addisonkeates]

y'all over here for math but im literally only here cus his voice holy-
