Answer 2

Let ABCD be a parallelogram in which ∠A = 65°

Since AD || BC we can treat AB as a transversal.

So ∠A + ∠B = 180° 65° + ∠B = 180° ∠B = 180° - 65°

∠B = 115°

Since the opposite angles of a parallelogram are equal,we have

∠C = ∠A = 65° and ∠D = ∠B = 115°

Hence, ∠B = 115°, ∠C = 65° and ∠D = 115°
