+
+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.
