Front

What are complementary angles?

Back

Two angles that add up to 90 degrees.

Front

What are supplementary angles?

Back

Two angles that add up to 180 degrees.

Front

What are vertical angles?

Back

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

Front

What are corresponding angles?

Back

Angles that are in the same position on different parallel lines cut by a transversal; they are equal.

Front

What are alternate interior angles?

Back

Angles that are on opposite sides of the transversal and inside the two lines; they are equal.

Front

What are alternate exterior angles?

Back

Angles that are on opposite sides of the transversal and outside the two lines; they are equal.

Front

What is the relationship between angles 2 and 7 if they are alternate exterior angles?

Back

They are equal.

Front

If angle A and angle B are supplementary, and angle A is 70 degrees, what is angle B?

Back

Angle B is 110 degrees.

Front

If two angles are vertical angles, and one angle measures 45 degrees, what is the measure of the other angle?

Back

The other angle also measures 45 degrees.

Front

What is the sum of the measures of complementary angles?

Back

The sum is 90 degrees.
