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 is an acute angle?

Back

An acute angle is an angle that measures less than 90 degrees.

Front

What is a right angle?

Back

A right angle is an angle that measures exactly 90 degrees.

Front

What is an obtuse angle?

Back

An obtuse angle is an angle that measures more than 90 degrees but less than 180 degrees.

Front

If one angle measures 120 degrees, what is the measure of its supplementary angle?

Back

The supplementary angle measures 60 degrees.

Front

If two angles add up to 90 degrees, what are they called?

Back

They are called complementary angles.

Front

What is the measure of a missing angle if the other angle is 76 degrees and they are supplementary?

Back

The missing angle measures 104 degrees.

Front

In a pair of adjacent angles, what does 'adjacent' mean?

Back

Adjacent angles are two angles that share a common side and a common vertex.

Front

If angle 2 is 45 degrees, what is the measure of an angle adjacent to it that is supplementary?

Back

The adjacent angle would measure 135 degrees.
