None.
Euler's characteristic requires that
V - E + F = 2
where V = number of vertices, E = number of edges and F = number of faces.
That equation is not satisfied by the numbers given in the question.

20 edges, 11 vertices (corners) and 11 faces.
Oh, dude, a nonagon has 9 faces, 27 edges, and 18 vertices. It's like a fancy way of saying a shape with nine sides. So, if you ever need to impress someone with your geometry knowledge at a party, there you go!
* 27 edges: 9 on each end face and 9 other edges between the side faces. * 11 faces: two end faces and 9 side faces. * 18 vertices: 9 on each end face.
