Question

pls solve this as I have a doubt​

Answer 1

Answer:

simply proving ∆PQO congruent to ∆PRO

by SAS rule is enough.

then angle POQ = angle POR

also QR is a straight line

then ANGLE POQ+ ANGLE POR = 180

THIS IMPLIES,

ANGLE POQ= ANGLE POR = 90°

HENCE proved that PS bisect QR at right angle
