This can be proved by the consecutive interior angles theorem which states that "If a transversal intersects two parallel lines, each pair of consecutive interior angles are supplementary (their sum is 180 ∘ ∘)." In the figure, m+y=180 o. This can be proved by showing that the angles inside the two lines and on the Same side of the transversal are supplementary (add to 180 degrees) than you can conclude the lines are parallel. We add the two consecutive interior angles to find their sum. If two lines are parallel to the same line, then they are parallel to each other. The two angles in the figure sum to so lines and are in fact parallel. Directions: Move point E or F and analyze the relationship between the measurements. If a pair of consecutive interior angles formed by a transversal are supplementary angles, the lines crossed are parallel lines. The consecutive interior angles converse states that If two lines are cut by a transversal so that consecutive interior angles are supplementary, then the lines are parallel. Usually you are given two parallel lines; but here you are given with two lines and have to prove that they are parallel. c and e are Consecutive Interior Angles.
