Parallel Lines Cut by a Transversal

Front

What is the angle relationship when two parallel lines are cut by a transversal and the angles are on opposite sides of the transversal and inside the parallel lines?

Back

Alternate Interior Angles

Front

What are supplementary angles?

Back

Angles that add up to 180°.

Front

What is the definition of corresponding angles?

Back

Angles that are in the same position on two parallel lines cut by a transversal.

Front

What is the relationship between vertical angles?

Back

Vertical angles are equal.

If two angles are complementary, what is the sum of their measures?

Back

90 degrees.

Front

What are alternate exterior angles?

Back

Angles that are on opposite sides of the transversal and outside the parallel lines.
