| alternate interior angles | two angles that are formed by two lines and a transversal and that lie between the two lines on opposite sides of the transversal |
| alternate exterior angles | two angles that are formed by two lines and a transversal and that lie outside the two lines on opposite sides of the transversal |
| consecutive interior angles | two angles that are formed by two lines and a transversal and that lie between the two lines on the same side of the transversal. also called same side interior angles |
| same side interior angles | two angles that are formed by two lines and a transversal and that lie between the two lines on the same side of the transversal. Also called consecutive interior angles |
