There is no maximum. For any integer n, there is a regular polygon (a 2-d shape) with n sides. And there are non-regular polygons as well.
5 edges, 5 verts, and faces are only on 3d shapes, for the most part, so any 2d shape has 1
It is called the perimeter. How you calculate it depends upon the type of shape it is.
a sopidocihedron
It's a 2D shape.
this is the shape of 2d cone
A Pentadecagon
it is a dodecagon
a 2d shape=4
it is a decagon
Definately a triangle
Every hexagon has.

A rhombus has 1 face (its a 2D shape) and has 4 edges. Its just a square pushed out of place. Hope this helps x
a sopidocihedron
Edges are sides in terms of 2D shapes but they are the place where two sides of a 3D shape meet ie. the sharp edge that runs between corners
The question is ambiguous. An octagon is a 2-dimensional shape with 8 edges and 8 vertices. Does a 3-D octagonal shape mean one with 8 edges or 8 faces or vertices, or faces which are 2d octagons?
