Applet that constructs quadrilaterals from (x,y) values of four given points.
The points are plotted counterclockwise. For convenience a set of sample data is given: 100 100 200 100 200 200 100 200
In Quadrille applet, a trapezium is a quadrilateral having only one pair of its opposite sides parallel, a trapezoid having none of its sides parallel. Please enable and open the Java Console to get the lengths and the slopes of the lines drawn.
