a and b are parallel lines, and c is a transversal. Name the relationship between ∠1 and ∠5. Parallel Lines Cut by a Transversal A line that crosses parallel lines is a transversal. If the transversal is not perpendicular to the parallel lines, then four angles are acute and four are obtuse. Exercises Use the figure to complete the reasons in the two-column proof to show that if lines b and e are parallel and cut by transversal a, then ∠1 is congruent to ∠ 3. From angles and parallel lines worksheets to maths parallel lines angles videos, quickly find teacher-reviewed educational resources. ∠3 and 5, 4 and 6 Alternate exterior angles are on opposite sides of the transversal and outside the parallel lines. Eight angles are formed. ∠1 and∠4 are corresponding angles.
