[RESOLVED] Calculating point position in space

[TheAgustin]

Hi there. My name is Agustin Garzon. I'm not a Math Guru
I'm a flash programmer trying to figure out how to solve a 2D problem for an animation I'm performing.

Basically, I know the position (x and y) of 5 points in a space. With that information, I must obtain the x and y position of a 6th point.
I've made a graph to clarify the problem:

I would extremelly appreciate any help you can provide. If you do so, please try to put it in form of an equation easy to understand.

Thanks a lot!
Agustin Garzon.
