[RESOLVED] Use Lines to draw Geometric Figures(Polygons)?

[Legjendat]

Hi guys. I'm trying to do something that is turning out to be out of my league at the moment. I need to draw geometric figures. These geometric figures have all the coordinates of their corners. Say I have a trapezoid, and I would want to draw it. The drawing would be done in a picturebox or a panel or a groupbox (some part of the form where only the geometric figure will be).

I saw the method on how to do that Here and that's exactly what I'm trying to achieve, but there it's drawn on a newly created form, and I need it in a picbox, panel or groupbox as I mentioned above. I also need the drawn figure to be at the center of the picbox/panel/groupbox. If anyone's willing to help, I'd really appreciate it.

The coordinates of the lines should be like (xa.text,ya.text) to (xa.text - xb.text, ya.text + yb.text) if I'm not wrong for the first line of the geometric figure and so on.
