Answer:Given Prove
PSUR is a rectangle QS = RT
PQ = TU
Proof:
Since PSUR is a rectangle, we know that opposite sides are parallel.
Therefore, PQ and TU are parallel.
Also, PSUR is a rectangle, so the angles P and R are right angles.
Therefore, angles Q and S are also right angles.
Since PQ and TU are parallel, and angles Q and S are right angles, we know that QS and RT are corresponding angles.
Therefore, QS=RT
QED.
