Source sentences:
text: As it happens, planar faces are always simple so for 3D polyhedra this distinction is trivial.
text: Polyhedra embedded in Euclidean space as manifolds (with multiple variations according to whether the faces are simple polygons, weakly simple, or polygons with holes, whether flat dihedrals are allowed, and whether the intersections of faces are restricted to single vertices or edges or whether they are unrestricted)
