Where two surfaces intersect, a line or curve is formed, depending on the nature of the surfaces. In three-dimensional geometry, the intersection can be a line if both surfaces are planes, or a curve if one or both surfaces are curved. This intersection represents all the points that are common to both surfaces. The specific characteristics of the intersection depend on the equations defining the surfaces involved.
Polymers, possibly.

The edge formed by two surfaces meeting each other is called a "corner" or a "boundary."
