Transversal:  A line that crosses two or more lines.
 Line: One of the basic undefined terms of geometry. A line has no thickness but its length goes on forever in two directions. Intersecting Lines: Two lines that cross each other. Lines intersect at one point unless the lines fall directly on top of each other (in which case they are essentially the same line and are sometimes called coincidental). Alternate Exterior Angles: Alternate exterior angles are pairs of angles formed when a third line (a transversal) crosses two other lines. These angles are on opposite sides of the transversal and are outside the other two lines. Alternate Interior Angles: Alternate interior angles are pairs of angles formed when a third line (a transversal) crosses two other lines. These angles are on opposite sides of the transversal and are in between the other two lines. Corresponding Angles: Angles that have the same relative positions in geometric figures.
