Here is the Code

        triangle1 = new Polygon();
        triangle1.addPoint(400, 550);        //left   
        triangle1.addPoint(600, 550); //right
        triangle1.addPoint(500, 350); //top
        triangle2 = new Polygon();
        triangle2.addPoint(600, 550);  // left
        triangle2.addPoint(700, 350); //top
        triangle2.addPoint(800, 550);  //right
        triangle3 = new Polygon();
        triangle3.addPoint(500, 350); //left
        triangle3.addPoint(700, 350); //right
        triangle3.addPoint(600, 150); //

try the below Values.

        Polygon triangle1 = new Polygon();
        triangle1.addPoint(100, 500); // first
        triangle1.addPoint(600, 500);//last
        triangle1.addPoint(350, 300);//middel

        Polygon triangle2 = new Polygon();
        triangle2.addPoint(350, 500); // first
        triangle2.addPoint(475, 400);//last
        triangle2.addPoint(225, 400);//middel
