Proving that two lines are parallel in euclidean geometry is something... Webb2 juni 2015 · Let the common tangent L be drawn. Then, by the Alternate Segment Theorem: ∠ D E A = ∠ ( D A, L) And similarly: ∠ C B A = ∠ ( C A, L) But the latter are equal as they are vertically opposite. Therefore it follows that the angles Intercepted by B E are equal and thus, the lines are parallel.

WebbThe two lines are parallel. By vertical angle theorem, ∠ b = 180 – d. By Transitive property of congruence, ∠ b = ∠ c. Similarly, you can prove that, ∠ a = ∠ d. We can also prove the converse of this theorem, according to which if two lines are cut by a transversal, then the alternate exterior angles are congruent. Let’s solve a ... Webb19 nov. 2024 · First, we have discussed about Parallel Lines and Transversals. A transversal is a line that intersects two or more coplanar lines at different points. The corresponding angles, alternate interior angles, alternate exterior angles formed by a transversal when it intersects a pair of parallel lines are congruent.
