Name the pairs of supplementary angles in the following figure: A, B, C, D, O

Solution:

Given, the figure represents two lines AB and CD which intersect at a point 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

∠AOD and ∠BOD

∠BOD and ∠BOC

∠BOC and ∠AOC

∠AOC and ∠AOD
