When a transversal cuts two lines, such that pairs of corresponding angles are equal, then the lines have to be parallel. ✘ When a transversal cuts two lines such that pairs of alternate interior angles are equal, then the lines have to be parallel. ✘ When a transversal cuts two lines such that pairs of interior angles on the same side of the transversal are supplementary, then the lines have to be parallel. ✘ When a transversal cuts two lines such that pairs of interior angles on the same side of the transversal are complementary, then the lines have to be parallel ✔
