Answer 2

Given  :

OR perpendicular to PQ

and OS is any ray between OP and OR

To Prove :  

<ROS = 1/2( <QOS - <POS)

Proof:

<ROS = <QOS - <QOR

<ROS = <QOS - <POR                   (OR perpendicular to PQ)

<ROS = <QOS - ( <ROS + <POS )

<ROS = <QOS - <ROS - <POS

2<ROS = <QOS - <POS

<ROS = 1/2( <QOS - <POS)

Hence Proved
