ASA, AAS, & HL

2. An __________is the common side of two consecutive angles in a polygon
An __________is the common side of two consecutive angles in a polygon. The following postulate uses the idea of an included side.

4. You can use the Third Angles Theorem to prove another congruence relationship based on ASA. This theorem is Angle-Angle-Side (AAS).
