What is Meant by Supplementary Angle?

In Maths, two angles are said to be supplementary, when the angles add up to 180 degrees. The supplementary angle need not be adjacent to each other, but its sum should be equal to 180 degrees. For example, 95° and 85° are supplementary angles.

Example:

To find out another angle if one of the supplementary angles is 100°

Solution:

We know that the sum of supplementary angles is 180°

Let the unknown angle be x

Thus,

100° + x = 180°

X = 180° – 100°

X = 80°

Hence, the unknown angle is 80°
