- x1 : the x-coordinate of the second point.
- y1: the y-coordinate of the second point. 

- x2 : the x-coordinate of the third point.
- y2: the y-coordinate of the third point. 



Example: 

this.setup = function()
{
   NCL = parent.NCL();
}
this.draw = function(scene)
{
   NCL.context.fillStyle = "red";
   NCL.triangle(10,10,10,20,20,20);
