Finding the complement and supplement for an angle in degrees

The video tutorial explains the concepts of complementary and supplementary angles. It defines complementary angles as two angles that add up to 90 degrees and supplementary angles as two angles that add up to 180 degrees. The tutorial demonstrates how to solve for unknown angles when one angle is given, using the example of a 98-degree angle. It highlights the limitation that a complement does not exist for angles greater than 90 degrees, as they cannot add up to 90 degrees with another positive angle.

What is the sum of two complementary angles?

• 90 degrees

• 180 degrees

• 270 degrees

• 360 degrees

What is the definition of supplementary angles?

• Two angles that add up to 270 degrees

• Two angles that add up to 90 degrees

• Two angles that add up to 180 degrees

• Two angles that add up to 360 degrees

If one angle is 98 degrees, what is the measure of its supplement?

• 82 degrees

• 90 degrees

• 180 degrees

• 98 degrees

Why can't an angle of 98 degrees have a complement?

• Because it is equal to 180 degrees

• Because it is greater than 90 degrees

• Because it is less than 90 degrees

• Because it is equal to 90 degrees

What happens when you subtract 98 from 180?

• You get the supplement of 98 degrees

• You get the complement of 98 degrees

• You get 98 degrees

• You get 180 degrees
