Complementary Angles

Front

What are complementary angles?

Back

Complementary angles are two angles whose measures add up to 90 degrees.

Front

If one angle measures 30 degrees, what is its complement?

Back

The complement of a 30-degree angle is 60 degrees.

Front

What is the sum of the measures of two complementary angles?

Back

The sum of the measures of two complementary angles is 90 degrees.

Front

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

Back

The complement of a 45-degree angle is 45 degrees.

Front

How do you find the complement of an angle?

Back

To find the complement of an angle, subtract the angle's measure from 90 degrees.

Front

What is the complement of an angle measuring 75 degrees?

Back

The complement of a 75-degree angle is 15 degrees.

Front

If two angles are complementary, and one angle measures 40 degrees, what is the other angle?

Back

The other angle measures 50 degrees.

Front

Can two angles be complementary if both are greater than 45 degrees?

Back

No, two angles cannot be complementary if both are greater than 45 degrees, as their sum would exceed 90 degrees.

Front

What is the relationship between complementary angles and right angles?

Back

Complementary angles sum up to form a right angle, which measures 90 degrees.

Front

If an angle measures x degrees, what is the expression for its complement?

Back

The expression for the complement of an angle measuring x degrees is (90 - x) degrees.
