In geometry, a uniform polyhedron is a polyhedron which has regular polygons as faces and is vertex-transitive (transitive on its vertices, isogonal, i.e. there is an isometry mapping any vertex onto any other).

A hendecahedron (or undecahedron) is a polyhedron with 11 faces. There are many topologically distinct forms of a hendecahedron, for example the decagonal pyramid, and enneagonal prism. Three forms are Johnson solids: augmented hexagonal prism, biaugmented triangular prism, and elongated pentagonal pyramid.

Feb 28, 2012 · Show that there is no polyhedron with exactly $11$ faces such that each face is a polygon having an odd number of sides.

An undecahedron is a polyhedron having 11 faces. Examples include those illustrated above and summarized in the following table.

In geometry, a polyhedron is a solid in three dimensions with flat faces and straight edges. Every edge has exactly two faces, and every vertex is surrounded by alternating faces and edges. The smallest polyhedron is the tetrahedron with 4 triangular faces, 6 edges, and 4 vertices.

Every polyhedron has three significant components viz faces edges and vertices. Faces: The flat surfaces that form a polyhedron are called its faces. These faces are two-dimensional polygons.

A polyhedron is a solid shape with flat faces and straight edges. Each face is a polygon (a flat shape with straight sides). Polyhedron comes from Greek poly- meaning "many" and -hedron meaning "face".

Polyhedrons are geometric figures of 3D space made up of a series of closed polygonal faces. The number of faces defines the geometric shape of the polyhedron.

Feb 4, 2015 · It turns out there are many polyhedra with $11$ vertices and $17$ edges. Even when we limit to convex polyhedra, there are $38$ topological distinct choices! The key of counting start from following little observation: $$2 \times 17 - 3\times 11 = 1\tag{*1}$$ The shape has $17$ edges.
