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.
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.
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".
