Parallel Lines Transversals Angle Relationships Vocabulary

Formed by two lines or rays, which meet at a point called a vertex

• perpendicular

• angle

• intersecting lines

• triangle

Lines that never meet or cross and stay the same distance apart

• perpendicular lines

• parallel lines

• intersecting lines

• transversal

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

• alternate exterior angles

• vertical angles

• corresponding angles

• same-side exterior angles

A pair of angles that occupy the same location at each intersection when two lines are intersected by one or more transversals

• complementary angles

• supplementary angles

• corresponding angles

• linear pair
