the other faces on a pentagonal prism would be rectangular
It is a dodecahedron - a shape with 12 faces which are regular pentagons.
A flat pentagon. Or some kind of circle pentagon breed...
It depends on what you mean by a 3-d pentagon. To most people, a 3-d pentagon is a dodecahedron - a 3d shape with 12 pentagonal faces. In that case, each of the faces, by definition, must be a pentagon! If you mean a pentahedron - a 3d shape with 5 plane faces, it could be a triangular prism or a quadrilateral based pyramid. In the first cae the bases are triangles, in the second, a quadrilateral.
A dodecahedron is a 3-d shape with 12 faces that are regular pentagons.
I'm assuming you mean a 3-d shape with faces of pentagons. This is called a Dodecahedron
A 3-d shape made from pentagonal faces is a dodecahedron (12 sides).
it is a decogonanon it is a decogonanon
The 3d shape that have five faces would be a triangular prism **************** or a pyramid
5 edges, 5 verts, and faces are only on 3d shapes, for the most part, so any 2d shape has 1
An edge of a 3-d pentagon is the intersection of two of its adjacent faces.
triangular prisom
The simplest such shape is PYRAMID.
