Good point about all triangles being equivalent given projection. In nailing down the angles, we've inadvertently defined a fourth vertex: the point of view. Given we're talking four vertices, we should maybe rename our class Tetrahedron ;-D.
Good solution - as it leaves open the question as to where is the triangle and where is the point of view ;) Though when we add another dimension, all tetras are projectively equivalent. Part of why I can't adjust to a focus on a tetra that happens to be regular in some way. Art
