They are called "faces".
Bipyramids are a class of polyhedra with more faces than vertices.
Regular polyhedra have identical faces.
There is not a term for a polyhedron with 2 congruent faces. There are multiple polyhedra with 2 congruent faces.
The flat surfaces of all polyhedra are called faces and a rectangular prism is simply one kind of polyhedron.
10 * * * * * Polyhedra are named according to the number of faces that they have. So a 3d dodecagon, called a dodecahedron would have 12 faces.
For convex polyhedra it is called the Euler characteristic.This requires that V - E + F = 2where V = number of vertices,E = number of edges andF = number of faces.
Polyhedra are named by the number of faces they contain. The names are based on Classical Greek. Over time, some polyhedra have become known by common, non-Greek names, i.e. a regular hexahedron is commonly called a cube.
There are a few families of polyhedra with identical faces. There are none whose faces have 6 or more sides. There is no special name for polyhedra whose faces are pentagons or pentagrams. A dodecahedron is an example. If coplanar faces are disallowed, the only polyhedron with quadrilateral faces are the cube and rhombohedron. There are infinitely many polyhedra with equilateral triangular faces: the tetrahedron, octahedron and icosahedron are examples.
It's a polyhedron. A polyhedron (plural: polyhedra) is a three - dimensional figure made up of sides called faces, each face being a polygon.
Strictly speaking, no. But, as the number of faces increases, polyhedra can approximate cylinders or spheres and so can "roll".
