Name the pairs of supplementary angles in the following figure: P, Q, R, S, O

Solution:

Given, the figure represents two lines PQ and RS intersecting at O.

We have to determine pairs of supplementary angles.

When the sum of the measures of two angles is 180°, the angles are called supplementary angles.

Linear pairs of angles are formed when two lines intersect each other at a single point.

Linear pair angles are supplementary angles as their sum is 180°.

From the figure,

The supplementary angles are

∠POS and ∠QOS

∠SOQ and ∠QOR

∠QOR and ∠ROP

∠ROP and ∠POS
