What is a transversal?

Back

A transversal is a line that intersects two or more other lines at different points.

Front

What are Alternate Interior Angles?

Back

Alternate interior angles are pairs of angles that lie between two lines and on opposite sides of a transversal. They are equal when the lines are parallel.

What are Corresponding Angles?

Back

Corresponding angles are pairs of angles that are in the same position on two different lines cut by a transversal. They are equal when the lines are parallel.

What are Consecutive Interior Angles?

Back

Consecutive interior angles are pairs of angles that lie on the same side of the transversal and between the two lines. They are supplementary when the lines are parallel.
