Definition of Complementary and Supplementary Angles

In geometry, complementary and supplementary angles are two types of angles with specific relationships in their measures.

Complementary anglesare two angles whose measures add up to 90 degrees. The formula for finding the measure of a complementary angle is:

measure of complementary angle = 90°

measure of given angle

Supplementary anglesare two angles whose measures add up to 180 degrees. The formula for determining the measure of a supplementary angle is:

measure of supplementary angle = 180°

measure of given angle

FAQ Overview: Complementary And Supplementary Angles Answer Key

What is the definition of complementary angles?

Complementary angles are two angles whose measures sum up to 90 degrees.

How do I calculate the measure of a supplementary angle?

To find the measure of a supplementary angle, subtract the measure of the other angle from 180 degrees.

Can you provide an example of a real-world application of complementary angles?
