Problem #4
These month we have a sequence of related questions:
- If two convex polyhedra have pairwise congruent faces, must
they be congruent?
- What if all of the faces are regular polygons?
- What if all of the faces of one (hence both) of the
polyhedra are congruent (but not necessarily regular)?
- What if all of the faces of one (hence both) of the
polyhedra are congruent and regular?
