Question

Quadrilateral RSTQ is a parallelogram.

Answer 1

Answer:

$\angle T \cong \angle R\\\angle S \cong \angle Q$

Step-by-step explanation:

According to the Parallelogram definition, every Parallelogram have a pair of congruent sides.  In this case, Namely $\overline{RS} \cong \overline{TQ}$  and $\overline{QR} \cong \overline{TS}$

(not listed as an option)

And the opposite angles are congruent too.

So

$\angle T \cong \angle R\\\angle S \cong \angle Q$
