If ABCD is a Parallelogram with 2 Adjacent angles∠A =∠B, then ...
If ABCD is a parallelogram, then opposite sides are equal in length and opposite angles are equal in measure.

Since ABCD is a parallelogram, we can say that angle A + angle C = 180 degrees (since consecutive angles of a parallelogram are supplementary).

If we are given that angle A and angle B are adjacent angles, then we can say that angle A + angle B = 180 degrees (since adjacent angles form a straight line).

Thus, we can conclude that angle A + angle C = angle A + angle B.

By subtracting angle A from both sides of the equation, we get angle C = angle B.

Therefore, angle B and angle C are equal in measure.
