### In a three dimentional view how many sides does a pentagon have?

A pentagon is a polygon that has 5 sides. It is a planar
geometric shape made of 5 line segments, and by definition, the
shape lies in a plane. It has only two dimensions. In the two
dimensions of the plane, the pentagon has five sides. By adding a
third dimention to view it, it still has only five sides because it
has no "thickness" owing to the fact that it is a geometric figure
confined to a plane. In either a two domentional view or a three
dimentional view, the pentagon has 5 sides. Adding another
dimention to view it will not "add any more sides" to the
pentagon.

### What is the shape of the bases on a 3-d pentagon?

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.
