Answer 1

According to the same side interior angle theorem, if a transversal line intersects two parallel lines, then each pair of same-side interior angles are supplementary.

From the given figure, it is seen that 72 degrees and 108 degrees are a pair of same-side interior angles that are supplementary to one another.

Hence the correct answer is (B)
