If both pairs of opposite sides of a quadrilateral are congruent, then it’s a parallelogram (converse of a property)

If both pairs of opposite angles of a quadrilateral are congruent, then it’s a parallelogram (converse of a property).

If The diagonals of a quadrilateral bisect each other, then it’s a parallelogram (converse of a property).

If one pair of opposite sides of a quadrilateral are both parallel and congruent, then it’s a parallelogram (neither the reverse of the definition nor the converse of a property).
