Knowing that QPT = ARZ, a congruent side pair is?

Answer:
[tex]\large\boxed{\overline{QT}\cong\overline{AZ}}[/tex]
Step-by-step explanation:
[tex]\triangle QPT\cong\triangle ARZ\\\\\begin{array}{c|c}Q&A\\P&R\\T&Z\end{array}\Rightarrow\begin{array}{ccc}\overline{QP}\cong\overline{AR}\\\overline{PT}\cong\overline{RZ}\\\overline{QT}\cong\overline{AZ}\end{array}[/tex]
Answer:
First option.
Step-by-step explanation:
I drew the triangles to see it better. If two triangles are congruent the sides and the angles have the same length. Also, the order of the vertex is important. I put them as it is enunciated. So, watching the image the congruent sides are:
QT and AZ
QP and AR
PT and RZ
Then, the correct option is the first one.
