Computational Geometry is *discrete* rather than *continuous*
Fundamental building blocks are the *point* and line *segment*.
*polygon*
: the closed region of the plane bounded by a finite collection of line segments
forming a closed curve that does not intersect itself. The segments are called *edges*
and the points where they meet are *vertices*. The set of vertices and edges is the *boundary*.
**Theorem 1.1: Polygonal Jordan Curve**
:The boundary $\partial P$ of a polygon $P$ partitions the plane into two parts.
In particular, the two components of $\Bbb{R}^2\setminus \partial P$ are the
bounded interior and the unbounded exterior.
