The quadrilateral formed b these points has sides with vertical and horizontal slopes. Therefore, the consecutive sides are perpendicular, making the quadrilateral a rectangle. The median meets the base at (0, 0), the midpoint of the base. Therefore, the median has undefined slope, or is vertical. ecause the base is a horizontal segment, the median is perpendicular to the base. The midpoints are ( a, 0), (a 1 d, e ), ( b 1 d, c 1 e ), and ( b, c ). ne pair of opposite sides has a slope of e, and the d other pair has a slope of c. Therefore, it b a is a parallelogram.
