And because the bases are parallel, we know that if a transversal cuts two parallel lines, then the consecutive interior angles are supplementary. 1 180 Parallel lines Proof 1 DRAFT. Because of the parallel sides, consecutive angles are same-side interior angles and are thus supplementary. and PART 2: prove that if the consecutive interior angles are equal, then (d) and (d') are parallel: also can be done by proving that triangles AKH and BKH' are similar triangles: they both have a common angle (at K), and two equal angles (the consecutive interiors, by hypothesis). Theorem: Two lines are parallel if and only if the two angles of any pair of consecutive interior angles of any transversal are supplementary (sum to 180°). Alternate exterior angles are congruent. Parallel Lines . Thus the Theorem 1 is fully proved. This theorem states that if two lines are cut by a transversal so that the consecutive interior angles are supplementary, then the lines are said to be parallel. 3 t STUDY. the quadrilateral abcd is a parallelogram, so by definition ab¯∥cd¯.
