Question

1. which of the following is not a method used to prove triangles congruent? aas theorem ssa postulate asa postulate sas postulate

Explanation:

• AAS Theorem: 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 two triangles are congruent.
• ASA Postulate: 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.
• SAS Postulate: If two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the two triangles are congruent.
• SSA Postulate: SSA (side - side - angle) does not always guarantee triangle congruence. For example, when we have two sides and a non - included angle, we can construct two different triangles in some cases.

Answer:

SSA Postulate
