Angle Review

Front

What are supplementary angles?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

Front

What are complementary angles?

Back

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

Front

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal.

Front

What are adjacent angles?

Back

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

Front

What is a linear pair of angles?

Back

A linear pair of angles consists of two adjacent angles that form a straight line, adding up to 180 degrees.

Front

If angle A is 30 degrees, what is the measure of its supplementary angle?

Back

The supplementary angle is 150 degrees, since 180 - 30 = 150.

Front

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

Back

The complementary angle is 45 degrees, since 90 - 45 = 45.

Front

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

Back

The sum is always 180 degrees.

Front

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

Back

The sum is always 90 degrees.

Front

Are vertical angles always equal?

Back

Yes, vertical angles are always equal in measure.
