Perform a translation that proves corresponding angles are always equal, and select the option which explains the proof. All right, so let's see what they have down here.

If we were to draw it-- and a lot of trickier geometry problems really all revolve around drawing the right lines or visualizing the right triangles. And I'll do one right here that might open up a lot for you in …

Course: High school geometry > Unit 2 Quiz 2 Quiz 2 Transformation properties and proofs

A fundamental part in geometry is the ability to write and use proofs to support your work. Khan Academy has recognized this by making video proofs of certain theorems (ex: proving the Law of …

Learn what it means for two figures to be congruent, and how to determine whether two figures are congruent or not. Use this immensely important concept to prove various geometric theorems about …

To improve at geometry proofs, start by understanding the problem and identifying what you’re given and what you need to prove. Familiarize yourself with key definitions, theorems, and properties, as …

"Module 1 embodies critical changes in Geometry as outlined by the Common Core. The heart of the module is the study of transformations and the role transformations play in defining congruence.

So I encourage you to pause the video and see if you can do that proof and I'll give you a little bit of a hint. It's going to involve the measure of the arcs that the various angles intercept.
