Angle Pairs Practice

Front

What are linear pair angles?

Back

Linear pair angles are two adjacent angles whose non-common sides form a straight line. They are supplementary, meaning their measures add up to 180 degrees.

Front

What is the supplement of an angle?

Back

The supplement of an angle is what, when added to the angle, equals 180 degrees. For example, the supplement of 74.3 degrees is 105.7 degrees.

Front

What are complementary angles?

Back

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

Front

What is the relationship between adjacent angles?

Back

Adjacent angles share a common side and a common vertex but do not overlap.

Front

What defines a linear pair of angles?

Back

A linear pair of angles consists of two adjacent angles that are formed when two lines intersect. They are always supplementary.

Front

If angle A is 30 degrees, what is its supplement?

Back

The supplement of angle A is 150 degrees, since 180 - 30 = 150.

Front

If angle B is 45 degrees, what is its complement?

Back

The complement of angle B is 45 degrees, since 90 - 45 = 45.

Front

Can two angles be both complementary and supplementary?

Back

Yes, the only pair of angles that are both complementary and supplementary are two angles that each measure 90 degrees.

Front

What is the sum of the measures of a linear pair of angles?

Back

The sum of the measures of a linear pair of angles is always 180 degrees.

Front

What is an example of a pair of complementary angles?

Back

An example of complementary angles is 30 degrees and 60 degrees, since 30 + 60 = 90 degrees.
