No. In a parallelogram, opposite angles are congruent.

Yes, opposite angles of a parallelogram are congruent.

the opposite angles are congruent

In all parallelograms, opposite angles and opposite sides are congruent. If all four sides are congruent, it's a rhombus. If all four angles are congruent, it's a rectangle. If all four sides and all four angles are congruent, it's a square.

If both pairs of opposite angles of a quadrilateral are congruent, then it is a parallelogram.
