Angle Addition
Channel: Andrew Misseldine
Date: 2022-02-04

In this video, we state and prove the Angle Addition Theorem. We also state and prove the Between Preservation Theorem of angle congruence, which states that when two angles are congruence any ray in the first angle can be translated onto the other so that corresponding parts are congruent. We also define the notion of a linear ordering of angles.
