Lines p and q are cut by a transversal. At the intersection of line p with the transversal, the bottom right angle is x. At the intersection of line q with the transversal, the bottom left angle is y and the bottom right angle is z. Letters x, y, and z are angle measures. Which equations would guarantee that lines p and q are parallel? Check all that apply. x = z x + y = 180° x + z = 180° x = y z = 180°
