I have a general question on an algorithm that I would like to use to construct an irregular polygon.
I have the following scenario: I have a start and end position for a ship, thus I know the distance between the two position (say 40km). Using this info, I would like to calculate the remaining vertices of a polygon that includes this as one side, while the other sides should be equal in length and sum up to say 200km (as a matter of fact, any user supplied length). I therefore know the perimeter of the resulting polygon and the 2 vertices that make up one of the sides.
In short, how do I get the other 4 vertices so that each side besides the initially calculated is the same size (and the perimeter of the hexagon adds up to 200 + initial side)?
Thanks in advance!
