Question

plz its urgent give me the answer plzzz​

Answer 1

Step-by-step explanation:

given-

RO is perpendicular to PQ

To prove- angleROS is equal to halfangle QOS-anglePOS

Proof-

since OR is perpendicular to PQ

hence,. angleROP is equal to 90 degree and ROQ is equal to 90 degree

we can say that angle ROPis eaual to angleROQ

angle POS+ angleROS is equal to angle ROQ

angle POS + angle ROS is equal to angle QOS- angle ROS

angle SOR+ angleROS is equal to angleQOS-angle POS

2 angle ROS is equal to angle QOS- anglePOS

angle ROS is equal to half angle QOS - anglePOS

hence proved
