4.3 Triangle Congruence by ASA and AAS • Postulate 4-3: Angle-Side-Angle (ASA) If two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the two triangles are congruent
4.3 Triangle Congruence by ASA and AAS • Theorem 4-2: Angle-Angle-Side (AAS) If two angles and a non-included side of one triangle are congruent to two angles and the corresponding non-included side of another triangle, then the triangles are congruent.
