an edge is a line segment joining two vertices in a PLOYGON

A face is a flat surface of a three-dimensional figure.

THE BOTTOM OR LOWEST PART OF SOMETHING

A corner.

cross section is the intersection of a figure in a 2-dimensional

surface area is the sum of all the areas of all the shapes that cover the surface of the object.
