Have you looked at
MoveTo(),LineTo(), et al?"One man's wage rise is another man's price increase." - Harold Wilson

Use analytic geometry this is easy to solve. A line can be defined by two points. You want another line that passes through a point and form a right angle with the first line. After you find the second line use GDI functions
MoveTo()andLineTo()to draw the second line.
