Complementary and Supplementary Angles

If angle B is 120 degrees, what is the measure of its supplementary angle?

• 60 degrees

• 30 degrees

• 90 degrees

• 150 degrees

How do you find the measure of a missing angle if you know one angle in a supplementary pair?

• Add the known angle to 90 degrees.

• Subtract the known angle from 180 degrees.

• Multiply the known angle by 2.

• Divide the known angle by 2.

If angle C is 75 degrees, what is the measure of its complementary angle?

• 15 degrees

• 30 degrees

• 45 degrees

• 60 degrees

What are supplementary angles?

• Two angles that add up to 90 degrees.

• Two angles that add up to 180 degrees.

• Two angles that are equal in measure.

• Two angles that are adjacent to each other.

What is the sum of the measures of supplementary angles?

• 90 degrees

• 180 degrees

• 360 degrees

• 45 degrees

What are complementary angles?

• Two angles that add up to 90 degrees.

• Two angles that add up to 180 degrees.

• Two angles that are equal in measure.

• Two angles that are adjacent to each other.

Can two angles be both complementary and supplementary?

• Yes, they can be both complementary and supplementary.

• No, because complementary angles add up to 90 degrees and supplementary angles add up to 180 degrees.

• Yes, if one angle is 45 degrees and the other is 135 degrees.

• No, because they must add up to the same total.

What is the measure of the missing angle if one angle is 156 degrees in a supplementary pair?

• 12 degrees

• 24 degrees

• 36 degrees

• 48 degrees

If angle D is 90 degrees, can it have a complementary angle? Why or why not?

• Yes, because complementary angles can be equal to 90 degrees.

• No, because complementary angles must add up to 90 degrees.

• Yes, because any angle can have a complementary angle.

• No, because complementary angles cannot be equal to 90 degrees.

What is the sum of the measures of complementary angles?

• 90 degrees

• 180 degrees

• 360 degrees

• 45 degrees
