Answer:
Step-by-step explanation:
QSR is congruent to SUT because vertically opposite angles, and common interior angles, and then QS is equal to ST. Which shows that they are congruent.
<S = <S, opposite angles
QS = ST, given
<R = <U, alternate angles QR//TU
by ASA, trangles QSR n TSU are congruent
