Question

#1: would you use sss or sas to prove the triangles congruent? if there is not enough information to prove the triangles congruent by sss or sas, choose
ot enough information\.

Explanation:

Step1: Identify congruent sides

We can see two pairs of corresponding sides are marked congruent: one pair with one tick, one pair with two ticks.

Step2: Identify included angles

The angles between these pairs of congruent sides are marked as right angles (so they are congruent, all right angles equal $90^\circ$).

Step3: Match to congruence rule

This fits the SAS (Side-Angle-Side) rule: two pairs of corresponding sides are congruent, and the included angles between them are congruent.

Answer:

SAS
