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

Answer 1

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.
