By using the theorem,
"If the diagonals of a quadrilateral bisect each other and have the same length, then the quadrilateral is a rectangle."
By the rectangle the opposite sides are equal and and the opposite angles are congruent.
Thus the Quadrilateral ABCD has all congruent sides and opposite angles that are congruent is given by Rectangle.
Answer:
