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

hello

hi, I don't think you have vertical angle for EGA, you don't have have two crossed lines here to say DGB.

Great

be less boring this is a tip

THIS VIDEO MAKES ME FELL ASLEEP

BOI

Subtitle is completly wrong

wow if my fucking screen would stop screwing up this video would be great

what about angle CGB or BGC, are they adjacent too?

Hey man, nice work! Can you tell me if a linear pair has a vertex, please? I'm pretty sure my teacher said "it does" with a sarcastic tone but I can't be sure.

@Khan Academy sir, may I know what application was used in this video? Is it a journal document?

This is exactly the lesson that I am teaching to my STEM students in 7th grade

Sal Khan says exactly what I did in class… but the kids like him more than me!

THANK YOU

this helps for my home work

Helped so much!! Thank you!!
