SAA CONGRUENCE POSTULATE If two angles of a triangle and a side opposite one of the two angles are congruent to the corresponding angles and side of another triangle, then the two triangles are congruent. ACTIVITY NO. 3 (1/2 crosswise) Prove the following. ACTIVITY NO. 4 (1/2 crosswise) For each pair of triangles, state the postulate that can be used to conclude the triangle to be congruent. (SSS, SAS, ASA and SAA) ACTIVITY NO. 5 (1/2 crosswise) For each set of triangles on ACTIVITY NO. 4, complete the triangle congruence statement.
