Understanding Complementary and Supplementary Angles

This video tutorial explains the concepts of complementary and supplementary angles. Complementary angles sum to 90 degrees, while supplementary angles sum to 180 degrees. The video provides examples and demonstrates how to calculate the complement and supplement of given angles, such as finding the complement of a 51-degree angle and the supplement of a 17-degree angle.

What is the sum of two complementary angles?

• 120 degrees

• 90 degrees

• 180 degrees

• 60 degrees

If two angles are complementary, what do they form when combined?

• An acute angle

• An obtuse angle

• A right angle

• A straight angle

What is the sum of two supplementary angles?

• 120 degrees

• 60 degrees

• 180 degrees

• 90 degrees

If two angles are supplementary, what do they form when combined?

• An acute angle

• A straight angle

• An obtuse angle

• A right angle

What is the complement of a 51-degree angle?

• 143 degrees

• 173 degrees

How do you find the supplement of an angle?

• Add the angle to 90 degrees

• Subtract the angle from 180 degrees

• Add the angle to 180 degrees

• Subtract the angle from 90 degrees
