For the figure below, if ∠1 = ∠5, then line l and line m are parallel to each other.
True
False
If a transversal intersects two parallel lines, then each pair of corresponding angles is equal.
Thus, whenever line AB parallel to CD are cut by a transversal t, then ∠1 = ∠5, ∠4 = ∠8, ∠2 = ∠6 and ∠3 = ∠7.
