Lesson 14. 2: Parallel Lines and Transversals Parallel lines are lines in the same plane that do not intersect.

Angles formed by Transversals A transversal is a line that intersects two or more coplanar lines at different points. • Angles that are between the two lines that are cut by the transversal are called interior angles. Angles 2, 4, 5 and 7 are interior angles. • Angles that are not interior angles are called exterior angles. Angles 1, 3, 6 and 8 are exterior angles.

Special Angle Pairs formed by Transversals form special pairs of angles: • Corresponding Angles • Alternate Interior Angles • Alternate Exterior Angles • Same side Interior Angles
