Vertical, adjacent and linearly paired angles | Geometry | Khan Academy

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.

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

got a test over this tomorrow this really helped

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!

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.

[alliahines]

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

[orion]

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

[sad_pepe]

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

[baad]

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