If you have 3 numbers then by definition it forms a plane, based upon

geometry.

I wonder if you really want to know the orientation of the plane. You can

go to

analytic geometry to get the equation for the plane, and from that get the

normal etc

and figure out everything you want. I suspect if you have a lot of triples

you could

program excel to do this for each triple of points.
