Angles - Complementary, Supplementary, Adjacent, Vertical

Front

What are vertical angles?

Back

Vertical angles are the opposite angles formed by the intersection of two lines. They are congruent, meaning they have equal measures.

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

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 the sum of the measures of complementary angles?

Back

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

Front

What is the sum of the measures of supplementary angles?

Back

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

Front

If two angles are vertical angles, what can be said about their measures?

Back

If two angles are vertical angles, their measures are equal.

Front

Can two angles be both complementary and supplementary?

Back

No, two angles cannot be both complementary and supplementary at the same time.

Front

What is an example of adjacent angles?

Back

An example of adjacent angles is the angles formed when two lines intersect, sharing a common vertex and side.

Front

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

Back

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