Given that a parallelogram is officially defined as a "quadrilateral with opposite sides that are equal," prove the property below. Property: In a parallelogram, a diagonal cuts the quadrilateral into two congruent triangles. (However, triangles formed by different diagonals are not necessarily congruent).
