Front

What is the measure of angle x if it is classified as obtuse?

Back

Angle x measures more than 90 degrees but less than 180 degrees.

Front

What is the relationship between two angles that share a common vertex and a common side but do not overlap?

Back

They are called adjacent angles.

Front

What are vertical angles?

Back

Angles that are opposite each other when two lines intersect; they are equal in measure.

Front

Back

Two angles that add up to 180 degrees.

Front

What are complementary angles?

Back

Two angles that add up to 90 degrees.

Front

If angle A is 70 degrees, what is the measure of its complementary angle?

Back

The complementary angle is 20 degrees.

Front

If angle B is 110 degrees, what is the measure of its supplementary angle?

Back
