Say I have triangles as shown:

triangles

Its easy to see that ABC is adjacent to ACJ: ABC and ACJ share 2 vertices (A and C).

However FEC and ACJ are also adjacent, but only one vertex is shared.

How can I find if two triangles are adjacent when they differ in size?

    Hmm... just to make sure we understand each other: the points A, B, ... are represented as Cartesian coordinates in your application?2010-09-05

    Lets say that yes, the points A, B .. are 3-space Cartesian coordinates. Is there another way you might prefer to represent them?2010-09-06
