Geometry and Solid Figures: Complementary and Supplementary Angles

- 

Two angles with a sum of degrees are called complementary angles.
- 

Two angles with a sum of degrees are Supplementary angles.



Examples:


Example 1.

Find the missing angle.
Solution: Notice that the two angles form a right angle. This means that the angles are complementary, and their sum is 90 Then:
The missing angle is 72 degrees.

Example 2.  Angles Q and S are supplementary. What is the measure of angle Q if angle S is 35 degrees? 
Solution: Q and S are supplementary


Example 3.  Angles and are complementary. What is the measure of angle if angle is 16 degrees? 
Solution: Angles and are complementary
