Question

which of the following is not a congruence theorem or postulate? a. aaa b. asa c. sas d. sss

Explanation:

ASA (Angle - Side - Angle), SAS (Side - Angle - Side), and SSS (Side - Side - Side) are valid triangle - congruence postulates. AAA (Angle - Angle - Angle) only guarantees similarity, not congruence as the side - lengths can be different for triangles with equal corresponding angles.

Answer:

A. AAA
