Dehn InvariantAn invariant defined using the angles of a 3-D Polyhedron. It remains constant under solid Dissectionand reassembly. However, solids with the same volume can have different Dehn invariants. TwoPolyhedra can be dissected into each other only if they have the same volume and the same Dehninvariant.
