Angle Measurer in C#

Question

I want to make a tool that can measure angles between two user defined spots on a form. I have no code to do this at the moment, so any code would be appreciated.

Answer 1

First you need to measure the distance between your points:

    public int Distance2D(int x1, int y1, int x2, int y2)
    {

        int result = 0;
        double part1 = Math.Pow((x2 - x1), 2);

        double part2 = Math.Pow((y2 - y1), 2);
        double underRadical = part1 + part2;
        result = (int)Math.Sqrt(underRadical);

       return result;
  }
