Front

What do you call a line that intersects two parallel lines?

Back

Transversal

Front

What are same side interior angles?

Back

Angles that are on the same side of the transversal and between the two parallel lines.

Front

If two parallel lines are cut by a transversal, what can be said about the alternate interior angles?

Back

They are equal.

Front

What is the sum of the interior angles on the same side of the transversal?
