Parallel Lines Cut by a TransversalTracy Driehaus 22 October 2012

Vertical Angles

Vertical angles are formed by the intersection of two lines and share a common vertex point. Vertical angles are congruent to one another.

Angles A & B are vertical angles.

Consecutive Interior Angles

Consecutive interior angles are on the same side of the parallel lines and the same side of the transversal. Consecutive interior angles are supplementary angles (their sum is 180 degrees.

Angles A & B are consecutive interior angles.
