4. State the converse of each of the following statements:
(a) If lines l and m are parallel, then a transversal to lines l and m cuts out congruent alternate interior angles.
(b) If the sum of the degree measures of the interior angles on one side of transversal r is less than 180°, then lines l and m meet on that side of transversal t. (See attached question file).
