Let's say I have 3 points, A B and C. Each point has a fixed distance to every other point.
If I want to find the right representation for those distances, I have to place A and B according to their distance, draw two circles respectively with center A and B and d(A, C) radius and d(B, C) radius.
The two intersections of the circles are the possible place where I can put C and have the right distance between every point.
Pretty simple. My problem is the following: How do I do the exact same thing with 4 points A B C and D ?
The two options for placing my C point never allow me to place D with the right distances from every other point.
(I am sorry if this is very badly explained, I'm not a native english speaker !)
Thanks you ! Gael
