real dihedral_angle  Protected static const variable 
The angle in radians between the faces of the Tetrahedron , namely
70 degrees
32'
.
Only
the Platonic polyhedra have a single dihedral angle, so
dihedral_angle is not a member of
Polyhedron . This means that it must be a member of all of the
classes representing Platonic polyhedra.

real triangle_radius  Protected variable 
The radius of the circle enclosing a triangular face of the
Tetrahedron .
