Question

which congruence property could you use to prove these two triangles are congruent?
○ sas
○ both sss and sas
○ neither sss or sas
○ sss

Explanation:

Step1: Identify marked congruent parts

In the triangles: one pair of sides has 1 congruence mark, one pair of sides has 2 congruence marks, and the angles between these two pairs of sides are marked as congruent.

Step2: Match to congruence rule

The SAS (Side-Angle-Side) rule states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, the triangles are congruent. We do not have all three sides marked congruent, so SSS does not apply.

Answer:

A. SAS
