A projective polyhedron is a type of polyhedron that can be associated with the projective plane, which is a two-dimensional geometric construct where points at infinity are considered, and lines intersect at those points. In simpler terms, the projective plane can be thought of as a plane in which parallel lines meet at a "point at infinity.
