Octahedron-In geometry, an octahedron is a polyhedron with eight faces. A regular octahedron is a Platonic solid composed of eight equilateral triangles, four of which meet at each vertex.
ReplyDeleteAn octahedron is the three-dimensional case of the more general concept of a cross polytope.
cube- a solid bounded by six equal squares, the angle between any two adjacent faces being a right angle.
ReplyDeletetetrahedron- Geometry. a solid contained by four plane faces; a triangular pyramid.
ReplyDeletedodecahedron- A polyhedron with 12 faces.
