For every polyhedron, there is a dual which is a polyhedron that has:a face where the first had a vertex,a vertex where the first had a face,the same number of edges.A self-dual polyhedron is a polyhedron whose dual is the same shape.All pyramids, for example, are self-dual.
That's a "vertex" of polyhedron or of her cousin tipi.
A vertex can be the corner of a polyhedron in which case at least three edges meet at a vertex.
Edges meet at a vertex.
It may be called an apex, but that is really only appropriate for a simple convex polyhedron.
The vertex is a point of polygon or polyhedra that is formed by 2 lines or 3 edges on a polyhedron.
An endpoint where two edges intersect on a polyhedron is called a vertex.
It's either a vertex, or the surface of the milkshake.
