Key Words Transversal- A line that intersects two coplanar (points that lie in the same plane) lines at two different points Corresponding Angles- If two lines are cut by a transversal, the non-adjacent interior and exterior angles on the same side of the transversal are the corresponding angles. Alternate Interior Angles- If two lines are cut by a traversal, the two angles on opposite sides of the transversal, but outside the two lines, are the alternate exterior angles.

Key Words Alternate Exterior Angles- If two lines are cut by a transversal, the two angles on opposite sides of the transversal, but outside the two lines, are the alternate exterior angles. Same-side Interior Angles- For two lines intersected by a transversal, a pair of angles that lie on the same side of the transversal and between the two lines.

Key Words Same Side Exterior Angles- If two parallel lines are intersected by transversal then exterior angles on the same side of the transversal.
