The relative to area of the middle quadrilateral

To illustrate the property of relative areas  of the middle and center quadrilateral, the applet includes two toolbars, onefor an odd N, and one for an even N, in which one can change the value of N using a toolbar, and obtain the relative area of the middle quadrilateral (or the two middle quadrilaterals). The applet is also to show that the segments that connect the middle points of the diagonals of each sub-quadrilateral have equal lengths and are parallel to each other.
