Answer: WWhen two parallel lines are cut by a third intersecting line, called a transversal line, eight angles are formed. These angles form different relationships with each other, one of them being same-side exterior. Same-side tells us that both angles are on the same side of the transversal line, and exterior tells us that both angles are exterior, or outside, of the parallel lines.
Two angles that are exterior to the parallel lines and on the same side of the transversal line are called same-side exterior angles. The theorem states that same-side exterior angles are supplementary, meaning that they have a sum of 180 or 190 degrees.
