Okay, so if you can find that it's the green and red lines you want, my solution will work for creating the polygon. (The average point will be somewhere in the middle and then G1, R1, R2, G2 are in order of angle from it.)

To find which lines you want, order them based on how far along the 'black axis' they cross the black lines, i.e. by r.b where r is any point on a line and b is the direction vector of the black lines.

(Sorry for not responding for a while, I forgot about this forum.)
