Answer 2

ok, you need to prove congruency

I'd pick triangles PQT and PTS

its easy to prove they are congruent by SAS postulate

then angle TPQ = TPS corresponding angles in congruent triangles

and angle SPQ = 90 as well as SPQ = TPQ + TPS

or 90 = 2TPQ (since you have equal angles)

then TPQ = 45... so the diagonal RP bisects SPQ
