Angle Pair Relationships

Angle Pair Relationships

When two parallel lines are intersected by a transversal, special angle pairs are formed. Click through each slide to review the different angle relationships.

​

Parallel Lines and Transversals

Corresponding Angles

​Congruent angles that lie in matching positions on the same side of the transversal.

​

​Alternate Interior

Angles

​Alternate Exterior

Angles

​Congruent angles that lie on opposite sides, inside the parallel lines.

​Congruent angles that lie on opposite sides, outside the parallel lines.

Same-Side Interior Angles

​Same-Side Exterior Angles

Supplementary Angles that lie on the same side of the transversal and inside the parallel lines.

Supplementary Angles that lie on the same side of the transversal and outside the parallel lines.
