The triangles created by the diagonals of this figure include one pair with equal areas, and the product of the areas of those triangles equals the product of the areas of the other two triangles.
The triangles created by the diagonals of this figure include one pair with equal areas, and the product of the areas of those triangles equals the product of the areas of the other two triangles. While these shapes' diagonals do not necessarily bisect each other, they must divide each other into segments of the same ratio. They must have two pairs of adjacent supplementary angles, and they are used for approximating integrals in a technique that is less accurate than Simpson's rule but more accurate than simple Riemann sums. The area of one of these can be calculated as height times median. Name these quadrilaterals that have at least one pair of parallel sides.
