Front

What are congruent angles?

Back

Angles that have the same measure. Examples include corresponding angles, alternate interior angles, and vertical angles.

Front

What are complementary angles?

Back

Two angles that add up to 90 degrees.

Front

What are corresponding angles?

Back

Angles that are in the same position on different parallel lines cut by a transversal. They are congruent.

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 congruent.

Front

What is a transversal?

Back

A line that intersects two or more lines at different points.

Front

What is the relationship between parallel lines and corresponding angles?

Back

When a transversal crosses parallel lines, the corresponding angles are congruent.

Front

What is the relationship between alternate interior angles and parallel lines?

Back

When a transversal crosses parallel lines, the alternate interior angles are congruent.

Front

If angle A and angle B are supplementary, and angle A measures 70 degrees, what is the measure of angle B?

Back

Angle B measures 110 degrees (180 - 70 = 110).

Front

If angle C and angle D are complementary, and angle C measures 30 degrees, what is the measure of angle D?

Back

Angle D measures 60 degrees (90 - 30 = 60).
