An octahedron is a closed 3-d shape with 8 polygonal faces. There are 257 topologically different convex octahedra. An octahedron can have 6 to 12 vertices, and 12 to 18 edges.

A sphere has no edges or edges but its face is globular.

A cone has 1 face, 0 edges, and one vertex. The face is the circular flat area. The cone can roll, so it has no edges. Edges have to be straight. The vertex is the pointy thing opposite to the face.

None but it's possible to construct shapes within a circle that have vertices.

Nothing, in particular. According to the Euler characteristic, regular polyhedra satisfy the following: Face + Vertices = Edges + 2 This gives Face + Vertices + Edges = 2 + 2*Edges = 2*(1+Edges) which, since it has the variable "edges" on the RHS as well, is not particularly helpful nor informative.

1 face 10 edges

One face and no edges

A regular dodecahedron, for example. Each face is a regular pentagon so no face has parallel sides. However, the edges on opposite faces are parallel to one another.

A cylinder has a circular face at each end, and a rectangular face folder around the middle. The only edges are the edges of the circular ends.

No edges, no corners, but it is considered to have 1 face.
