The polygon angle sum theorem says that the angles of a polygon with n sides is equal to n-2 180. In geometry, a transversal is a line that passes through two lines in the same plane at two distinct points.Transversals play a role in establishing whether two or more other lines in the Euclidean plane are parallel.The intersections of a transversal with two lines create various types of pairs of angles: consecutive interior angles, corresponding angles, and alternate angles. Q. If you put two supplementary angle pieces together, you can draw a straight line across the top of the two angles. Supplementary angles are pairs of angles that add up to 180 degrees. A and W. C and X. alternate exterior angles… About the Book Author. 1) y x corresponding 2) y x alternate exterior 3) y x corresponding 4) y x consecutive interior 5) y x alternate interior 6) y x alternate exterior 7) y x alternate interior 8) y x Some of them are absolutely free of cost! Do alternate exterior angles prove that the lines are parallel? corresponding angles. To help you remember: the angle pairs are on Alternate sides of the Transversal, and they are on the Interior of the two crossed lines.. The angles which are formed inside the two parallel lines, when intersected by a transversal, are equal to its alternate pairs. answer choices . 0 0. The figure above shows two pairs of alternate interior angles. If the lines are parallel, then the alternate interior angles … Alternate angles are equal. 126.
