Query: Recognition of affine-equivalent polyhedra by their natural developments   The classical Cauchy rigidity theorem for convex polytopes reads that if two
convex polytopes have isometric developments then they are congruent. In other
words, we can decide whether two polyhedra are isometric or not by using their
developments only. In this article, we study a similar problem about whether it
is possible, using only the developments of two convex polyhedra of Euclidean
3-space, to understand that these polyhedra are (or are not) affine-equivalent.
