Yes, coolul007 is correct, that would have helped a lot if the center of the sphere can be defined.

Thank you for the contribution, coolul007: unfortunately its not the case in irregular tetrahedron. haruspex: It looks like I must go through these equations and see what i get, they look very ugly though. do you think adding another equation using the volume of the tetrahedron, which is 1/6...

This is my first post and I wish to get help in finding an analytically way to get the coordinate of an irregular tetrahedron. let ABCD be the 4 vertices of the tetrahedron in 3D, all vertices have different (x,y,z). the coordinate of vertex D is known (Xd,Yd,Zd), and the 3 angle between...
