Front

What are parallel lines?

Back

Front

What is a transversal?

Back

A line that crosses at least two other lines in the same plane.

Front

What are corresponding angles?

Back

Angles that are in the same position on two 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 two lines.

Front

What are alternate exterior angles?

Back

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

Front

What are consecutive interior angles?

Back

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

Front

What is the relationship between corresponding angles when lines are parallel?

Back

They are equal.

Front
