Name the pairs of supplementary angles in the following figure: 1, 2, 3, 4, 5, 6

Solution:

Given, the figure represents three lines in the form of a triangle.

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

∠1 and ∠2

∠3 and ∠4

∠5 and ∠6
