= 110o. Prove: m<2 = 70 degrees.


A) Opposite angles of a parallelogram are supplementary; m<1 + m<2 =180.
B) Consecutive angles of a parallelogram are supplementary; m<1 + m<2 = 90.
C) Consecutive angles of a parallelograms are congruent; <1 is congruent to <2
D) Consecutive angles of a parallelogram are supplementary; m<1 + m<2 = 180.
