Understand dimensions and how these elements form shapes and patterns. Learn key geometric terms like colinear points, midpoints, and vertices, and enhance your knowledge of geometry. Improve your skills and discover the world of shapes and space. Created by Sal Khan.
An angle is two rays that share a vertex . One ray extends upward and to the right from point A. A second ray extends downward and to the right from point A. Intersecting lines or line segments also form angles. Two lines intersect with each other. One line extends from top to bottom.

And line DE, are indeed, parallel lines. So we wanna prove that these two things, that the measure of these two angles are equal. So, there's many ways that you can do this geometrically. And we do that in many Khan Academy videos, but this one, they offer us the option of translating, of doing a translation, so let's see what that is.
