If a transversal intersects two parallel lines, then which of the pair

1.	If a transversal intersects two parallel lines, then which of the pairs of angles is equal?
Answer» ∠1 = ∠4 ( vertically opposite angle)∠1 = ∠5 ( corresponding angles)∠4 = ∠5 ( alternative angles) Similarly∠2 = ∠3 ( vertically opposite angle)∠2 = ∠6 ( corresponding angles)∠3 = ∠6 ( alternative angles)

Answer»

∠1 = ∠4 ( vertically opposite angle)∠1 = ∠5 ( corresponding angles)∠4 = ∠5 ( alternative angles)

Similarly∠2 = ∠3 ( vertically opposite angle)∠2 = ∠6 ( corresponding angles)∠3 = ∠6 ( alternative angles)
