Complementary and Supplementary Angles

Front

What are complementary angles?

Back

Two angles are complementary if the sum of their measures is 90 degrees.

Front

What are supplementary angles?

Back

Two angles are supplementary if the sum of their measures is 180 degrees.

Front

If one angle is 30 degrees, what is the measure of its complementary angle?

Back

The complementary angle would be 60 degrees, since 30 + 60 = 90.

Front

If one angle is 110 degrees, what is the measure of its supplementary angle?

Back

The supplementary angle would be 70 degrees, since 110 + 70 = 180.

Front

If one angle is 45 degrees, what is the measure of its complementary angle?

Back

The complementary angle would be 45 degrees, since 45 + 45 = 90.

Front

If one angle is 80 degrees, what is the measure of its supplementary angle?

Back

The supplementary angle would be 100 degrees, since 80 + 100 = 180.

Front

What is the measure of a complementary angle if one angle is 25 degrees?

Back

The complementary angle would be 65 degrees, since 25 + 65 = 90.

Front

If one angle is 150 degrees, what is the measure of its supplementary angle?

Back

The supplementary angle would be 30 degrees, since 150 + 30 = 180.

Front

What is the measure of a supplementary angle if one angle is 95 degrees?

Back

The supplementary angle would be 85 degrees, since 95 + 85 = 180.

Front

What is the measure of a complementary angle if one angle is 35 degrees?

Back

The complementary angle would be 55 degrees, since 35 + 55 = 90.
