A closed three-dimensional figure formed by four or more polygons that intersect only at their edges is called a polyhedron. It contains flat faces, straight edges, and sharp corners or vertices.
A polyhedron is a 3 dimensional figure made of polygons. A cylinder is made of two circles and a rectangle around the middle. Since circles are not considered polygons (don't have straight edges), a cylinder cannot be a polyhedron. I just had a discussion about this with my math students today.
No, they are the faces of the polyhedron.
An irregular polyhedron is a solid shape in which either all edges are not the same length, or all faces are not congruent polygons or all [solid] angles are not of the same measure.
A solid figure that has flat faces that are polygons is called a polyhedron. Polyhedra have various forms, such as cubes, tetrahedra, and octahedra, each defined by the shape and number of their polygonal faces. The faces of a polyhedron are connected by edges, and the points where the edges meet are called vertices. Examples include regular polyhedra, where all faces are identical polygons, such as the Platonic solids.
It is unlikely that the question is about a polyhedron which is a 3-dimensional solid bounded by polygons. The minimum number of edges for a polyhedron is 6: the question appears to suggest just 4.
They are the faces of the polyhedron.
A shape in fewer than 3 dimensions.A shape with one or more curved faces or edges.
A polyhedron is a solid object bounded by polygons. Polygons are plane shapes [bounded by straight lines]. The curved surface of a cone is not a polygon and so the cone is not bounded by polygons and therefore, a cone is not a polyhedron.
