No - we don't do your homework for you! Laugh | :laugh:
But... some hints.
I you don't need a picture box: use a Panel instead.
Handle the Mouseclick event for the Panel, and capture three clicks:
Origin (x, y)
p1 (x1, y1)
p2 (x2, y2)
The click Location is provided in the MouseEventArgs and are relative to the Panel.
Invalidate the Panel for each click.
Handle the Paint event for the panel.
Draw a circle at each point (if provided) using Graphics.DrawEllipse and the lines as points become available using Graphics.DrawLine
Once you have the three points, you can calculate the angle with simple trig.
Wolfram MathWorld[^] can give you the equation if you search it for "Line-Line Angle"
Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...
