First, write a congruency statement. Remember that corresponding vertices must appear in the same order.

QPO ≅

TUS

You know that

QPO ≅

TUS, which means that

QPO is congruent to

TUS. Find the angle in

TUS that corresponds to Q.

Q ≅ T

Since Q ≅ T, the two angles have the same measure.

According to the figure, m

T = 59°. So, m

Q = 59°.
