Since the opposite angles in a parallelogram are congruent, we have:∠A = 39°∠B = 27°∠C = 39°∠D = 27°
Therefore, all angles of parallelogram ABCD are determined.
Since the opposite angles in a parallelogram are congruent, we have:
∠A = 39°
∠B = 27°
∠C = 39°
∠D = 27°
Therefore, all angles of parallelogram ABCD are determined.
