1. 4.5 Proving Congruence – ASA and AAS
What you’ll learn:
To use the ASA Postulate to test for triangle congruence.
To use the AAS Theorem to test for triangle congruence.

2. 2 more ways to prove 2 triangles 
Postulate 4.3 Angle-Side-Angle Congruence If 2 angles and the included side of one triangle are congruent to 2 angles and the included side of another triangle, then the triangles are congruent. Theorem 4.5 Angle-Angle-Side Theorem If 2 angles and a nonincluded side of one triangle are congruent to the corresponding 2 angles and side of a 2nd triangle, then the 2 triangles are congruent.
