[Tlhingan-hol] geometry terminology in Klingon

With respect, that's not true. ANY polyhedron with four triangular faces, regardless of the dimension of said faces, is a tetrahedron. You're thinking of the *regular* tetrahedron (one of the five Platonic solids and so the best-known tetrahedron), but there is such a thing as an irregular tetrahedron too:

Whether a Klingon would refer to an irregular tetrahedron like this one as a {qu'vu'} is another question, of course:

but where not every tetrahedron may be a {qu'vu'}, every {qu'vu'} would be a tetrahedron.
