Parallel lines angles theorem
WebMar 4, 2024 · If a transversal intersects two parallel lines, then the pair of alternate interior angles are equal. From the above figure, the following pairs of alternate interior angles are equal: ∠3 = ∠5 and ∠4 = ∠6. We can also prove this theorem as ∠4=∠2 and ∠1=∠3 (Vertically opposite angles). Also, ∠1=∠5 and ∠2=∠6 (Corresponding Angles) WebThis postulate means that only one parallel line will pass through the point Q, no more than two parallel lines can pass at the point Q. Postulate of lines cut by a transversal. If two …

WebJan 11, 2024 · Alternate Exterior Angles Made By A Transversal And Parallel Lines. Angles can be equal or congruent; you can replace the word "equal" in both theorems with "congruent" without affecting the theorem. So if ∠B and ∠L are equal (or congruent), the lines are parallel.You could also only check ∠C and ∠K; if they are congruent, the lines are …
