Back

Two angles that add up to 180 degrees.

Front

What are vertical angles?

Back

Angles opposite each other when two lines cross, they are equal.

Front

What are corresponding angles?

Back

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

Front

What are alternate interior angles?

Back

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

Front

What is the relationship between parallel lines and transversals?

Back

Transversals create various angle relationships when they intersect parallel lines.
