The Congruence Axioms for Angles

In this video, we introduce the notions of congruence of angles  and triangles and present the three congruence axioms related to angle congruence, namely Angle Translation, Transitivity of Angle Congruence, and Side-Angle-Side. We state that angle congruence is an equivalence relation.
