Each pair of these angles are outside the parallel lines, and on the same side of the transversal. When two lines intersect each other, then the pair of opposite angles formed at the vertex are called vertical angles. Consecutive angles theorem or consecutive interior angles theorem states that two consecutive interior angles are always supplementary angles. Taking one exterior angle.
