Mei draws three pairs of parallel lines that are each intersected by a third line. in each figure, she measures a pair of angles. what is a reasonable conjecture for mei to make by recognizing a pattern and using inductive reasoning? a. when a pair of parallel lines are intersected by a third line, the alternate interior angles are congruent. b. when a pair of parallel lines are intersected by a third line, the alternate interior angles are acute. c. when a pair of parallel lines are intersected by a third line, all of the angles formed are obtuse. d. when a pair of parallel lines are intersected by a third line, all of the angles formed are congruent.
