In the figure, line L1 is parallel to line L2. If the measure of ∠4 = 144°, what is the measure of ∠6 and why? A. 144°, vertical
angles have the same measure B. 144°, corresponding angles have the same measure C. 36°, same side interior angles are supplementary D. 36°, alternate exterior angles are supplementary
Since ∠4 and ∠6 angles formed on the same side interior angles and the same-side interior angles that are formed are supplementary, or add up to 180 degrees.
