The problem goes as follows……

There is an irregular tetrahedron ABCD . the length AB BC AC AD BD CD that is the length of the 6 edges of the tetrahedron are known. The coordinates of one of the faces say ABC is known . let the coordinates be A(x1 y1 z1) B(x2 y2 z2) and C(x3 y3 z3) . with these given data I want to determine the coordinates of the fourth point that is D.

If any one can suggest an analytical approach to solve this problem with these given datas
