Step-by-step explanation:
Whether given two lines are parallel or not can be decided by examining the angles formed by a transversal of the lines
(1) If the interior angles on the same side of a transversal are supplementary then the lines (2) If one of the pairs of alternate angles is congruent then the lines are parallel
