Question

POQ is a line.ray OR is perpendicular to line PQ.OS is another ray lying between rays OP and OR.prove that angle ROS(angle QOS - angle POS

Answer 1

Step-by-step explanation:

to prove:- <Ros=1/2(<qos-<POS)

<por=<roq (right angle 90 degree)

<pos+<sor=<qos-<sor

2<sor=<qos-<POS

<sor=1/2(<qos-<POS)
