Exploring Complementary and Supplementary Angles

If angle A and angle B are complementary and angle A measures 35 degrees, what is the measure of angle B?

• 45 degrees

• 70 degrees

• 90 degrees

• 55 degrees

A right angle is formed by two complementary angles. If one angle measures 45 degrees, what is the measure of the other angle?

• 60 degrees

• 30 degrees

• 45 degrees

• 90 degrees

In a triangle, one angle measures 70 degrees and another angle measures 40 degrees. Are these angles complementary or supplementary?

• The angles are supplementary because they are less than 90 degrees

• Neither complementary nor supplementary

• The angles add up to 110 degrees

• The angles are both acute

Two angles are supplementary. If one angle measures 110 degrees, what is the measure of the other angle?

• 70 degrees

• 90 degrees

• 60 degrees

• 100 degrees

A pair of complementary angles is used in a design. If one angle measures 25 degrees, what is the measure of the other angle?

• 90 degrees

• 30 degrees

• 65 degrees

• 45 degrees

If angle X is 60 degrees and angle Y is supplementary to angle X, what is the measure of angle Y?

• 90 degrees

• 150 degrees

• 180 degrees

• 120 degrees

In a classroom, two angles are formed by the intersection of a desk and a wall. If one angle is 90 degrees, what is the measure of the other angle if they are supplementary?

• 90 degrees

• 180 degrees

• 60 degrees

• 45 degrees

A sports field has a corner that forms a right angle. If one angle is 30 degrees, what is the measure of the other angle that is complementary to it?

• 60 degrees

• 45 degrees

• 90 degrees

• 75 degrees

Two angles are complementary. If one angle measures 50 degrees, what is the measure of the other angle?

• 60 degrees

• 70 degrees

• 30 degrees

• 40 degrees

If angle C measures 120 degrees, what is the measure of the angle that is supplementary to angle C?

• 30 degrees

• 60 degrees

• 150 degrees

• 90 degrees
