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
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
Octagon
