NO LINKS OR ELSE YOU'LL BE REPORTED! Only answer if you're very good at Math. PRS is isosceles with RP=RS. RQ is drawn such that it bisects <PRS. What additional fact can be used to prove PRQ = SRQ by SAS in order to state that <P = <S because they are congruent parts of congruent triangles?

A: PQ = SQ

B: RQ = RQ

C: <PQR = <SQR

D: RQ PS​
