Question

1. which criterion for triangle congruence involves two sides and the included angle?

a. sas
b. aas
c. sss
d. asa

Explanation:

• SAS (Side - Angle - Side): This congruence criterion states that if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, then the two triangles are congruent.
• AAS (Angle - Angle - Side): Involves two angles and a non - included side.
• SSS (Side - Side - Side): Involves three sides.
• ASA (Angle - Side - Angle): Involves two angles and the included side.

Since the question asks for the criterion with two sides and the included angle, we focus on the definitions.

Answer:

A. SAS
