Which of the following facts, if true, would allow you to prove that lines l and m are parallel?Two horizontal lines are shown and they are labeled l and m. They are cut by a transversal. The transversal intersects line l at the top of the image, creating four angles labeled 1, 2, 3, and 4. Angle 1 is in the top left corner. Angle 2 is in the top right corner. Angle 3 is in the bottom left corner. Angle 4 is in the bottom right corner. The transversal intersects line m at the bottom of the image, creating four angles labeled 5, 6, 7, and 8. Angle 5 is in the top left corner. Angle 6 is in the top right corner. Angle 7 is in the bottom left corner. Angle 8 is in the bottom right corner.
The angles formed by the transversal and the lines l and m are corresponding angles. If the measure of angle 1 is equal to the measure of angle 6, then lines l and m are parallel.
