Local Geometry of Polyhedra and Cauchy’s Rigidity Theorem
Université du Littoral Côte d'Opale, Calais, France
We give a formula that relates internal and external angles of polyhedra with some geometric applications, and apply it for a new proof of the celebrated Cauchy’s rigidity theorem.
Keywords: Local geometry, polyhedra, Cauchy’s rigidity theorem, new proof.
