Parallel Lines Transversals Angle Relationships Perpendicular Lines

When two lines are cut by a transversal, a pair of angles on opposite sides of the transversal and outside the two lines

• same-side exterior angles

• alternate interior angles

• complementary angles

• alternate exterior angles
