Why is any quadrilateral figure a parallelogram?

Not every quadrilateral is a parallelogram; however, a quadrilateral can be classified as a parallelogram if it satisfies specific conditions, such as having both pairs of opposite sides parallel and equal in length. Additionally, if one pair of opposite sides is both parallel and equal, or if the diagonals bisect each other, then the quadrilateral is also a parallelogram. Thus, while all parallelograms are quadrilaterals, not all quadrilaterals meet the criteria to be classified as parallelograms.
