Question

In the diagram below, ΔPQR ≅ ΔSTR. Complete the statement ∠Q ≅ ___

Answer 1

Answer:  Choice A.  $\angle T$

Explanation:

Notice how letters Q and T are in the middle of the sequences of PQR and STR respectively. This means the angles correspond.

Because the triangles are congruent, this means the corresponding pieces are congruent. Therefore, angle Q and angle T are the same measure.

As you can see, the order matters when it comes to forming congruence statements. Something like $\triangle PQR \cong \triangle STR$ is slightly different from $\triangle PQR \cong \triangle SRT$
