If two parallel planes are cut by a third plane, the lines of intersection will be parallel. A transversal is a line that intersects two or more coplanar lines. Alternate interior angles and same side interior angles are pairs of angles related to a transversal. Corresponding angles are in corresponding positions relative to two lines.2-5
