Answer 2

Answer:

Step-by-step explanation:

Given,

OR is perpendicular to line PQ

To prove,

∠ROS = 1/2(∠QOS – ∠POS)

A/q,

∠POR = ∠ROQ = 90° (Perpendicular)

∠QOS = ∠ROQ + ∠ROS = 90° + ∠ROS --- (i)

∠POS = ∠POR - ∠ROS = 90° - ∠ROS --- (ii)

Subtracting (ii) from (i)

∠QOS - ∠POS = 90° + ∠ROS - (90° - ∠ROS)

⇒ ∠QOS - ∠POS = 90° + ∠ROS - 90° + ∠ROS

⇒ ∠QOS - ∠POS = 2∠ROS

⇒ ∠ROS = 1/2(∠QOS – ∠POS)

Hence, Proved.
