This construction creates equidiametrals figures, ie at all times that each point of the border of the figure has constant distance from the opposite point
To start press " > " to start the movement. You can modify the points E, F , G, H , I, J , K , L in height to generate different equidiametrales figures. To verify that the figure actually is equidiametral can help visualization of a circle whose diameter is the R , R ' segment (to view click on the " DiametroCircunferencia " box ) Why the screen above shows only the X axis values 0-2 PI? Why can not modify the values of E ', F ', G ' , H' , I ', J' , K ' , E' '? Why does not exist L ' and instead appears E' '?
