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. simucube button plateWebbthat as long as we have one pair of alternate interior angle congruent, the lines will be parallel, so the two line will be parallel if we could prove \4 ˘=\6, or \3 ˘=\5. The converse of the theorem says that, when two lines are parallel, then all corresponding angles are congruent, so given that ABjjCD, then \4 ˘=\6, and \3 ˘=\5. simufact forming官网

In the figure, a line parallel to side 𝐵 𝐶 is intersecting the other two sides of the triangle. The side splitter theorem tells us that this line divides those sides proportionally. Labelling this line segment as 𝐷 𝐸, we obtain 𝐴 𝐷 𝐷 𝐵 = 𝐴 𝐸 𝐸 𝐶.
