Parallel Lines and Intersections

A pair of angles on the outer side of the two parallel lines but on the opposite side of the transversal line.

• Interior Angles

• Alternate Interior Angles

• Alternate Exterior Angles

• Exterior Angles

Two angles that lie in similar relative positions on the same side of a transversal line or at each intersections.

• Interior Angles

• Corresponding Interior Angles

• Corresponding Exterior Angles

• Corresponding Angles

If a transversal line intersects a pair of parallel lines, then the sum of the consecutive interior angles is equal to 180 degrees forming a supplementary angles

• Interior Angles

• Consecutive Interior Angles

• Corresponding Exterior Angles

• Corresponding Angles
