Question

1. determine how the triangles below are congruent.

Explanation:

Step1: Identify congruence criteria

The marks on the sides of the triangles show that three pairs of corresponding sides are equal.

Step2: Recall SSS congruence

The Side - Side - Side (SSS) congruence postulate states that if three sides of one triangle are congruent to three sides of another triangle, the two triangles are congruent.

Answer:

The triangles are congruent by the SSS (Side - Side - Side) congruence postulate.
