In Fig. 5.43, write all the pairs of supplementary angles

Solution:

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

We have to write all the pairs of supplementary angles.

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

From the figure,

The pair of supplementary angles are

∠7 and ∠2

∠1 and ∠8

∠4 and ∠5

∠4 and ∠3

∠3 and ∠6

∠6 and ∠5
