Front

What is a right angle?

Back

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

Front

What is an acute angle?

Back

An acute angle is an angle that measures less than 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

Front

What is the sum of the interior angles of a triangle?

Back

The sum of the interior angles of a triangle is always 180 degrees.

Front

What is the measure of an angle that is complementary to a 30-degree angle?

Back

The measure of the complementary angle is 60 degrees, because complementary angles sum to 90 degrees.

Front

What is the measure of an angle that is supplementary to a 120-degree angle?

Back

The measure of the supplementary angle is 60 degrees, because supplementary angles sum to 180 degrees.
