What are adjacent angles?

Back

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

Front

What does the term 'congruent' mean?

Back

Congruent means having the same measure.

Front

What are vertical angles?

Back

Vertical angles are angles that are opposite each other when two lines intersect and are congruent.

Front

What are complementary angles?

Back

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

Front

What are supplementary angles?

Back

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

Front

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

Back

The measure of the complement of angle A is 60 degrees (90 - 30 = 60).

Front

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

Back

The measure of the supplement of angle B is 60 degrees (180 - 120 = 60).

Front

True or False? Angles that are adjacent can be congruent.

Back

True, adjacent angles can be congruent if they have the same measure.

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

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

Back

The sum of the measures of two supplementary angles is 180 degrees.
