Question

transversal intersects two lines each pair of interior angles on the same side of theTransversal is supplementary.

Answer 1

Answer:

The Theorem is that If a transversal intersects two parallel lines, then each pair of co-interior angles is supplementary (their sum is 1800). Conversely, if a transversal intersects two lines such that a pair of co-interior angles is supplementary, then the two lines are parallel.
