Hello Opus, thank you for your input. Sorry I edited my post a few minutes after writing it as I realized that a circle would be easier then a square. In any case the black circle is just for distance purpose in the final result it will be invisible.

How would I calculate the .Left and .Top of the imgDirection once I calculate that distance? As the endpoint of the line is the radius with an angle inside a picturebox. However the coordinates I need is for the imgDirection which is .Left amd .Top. Any ideas?
