Ina is given the theorem and diagram below. She constructs the outline of a proof below to show that lines w and x are parallel.
Consecutive Interior Angles Theorem: If two lines are parallel, the interior angles on the same side of a transversal that crosses the lines are supplementary.
Given: lines w and x intersected by line t; and are congruent.
Prove:
