The theorem states that if both pairs of opposite sides of a quadrilateral are congruent, then the quadrilateral is a parallelogram. This is a fundamental result in geometry (a subfield of Mathematics) related to the properties of parallelograms. By the definition and properties of parallelograms, a quadrilateral with both pairs of opposite sides congruent satisfies the criteria for being a parallelogram.
