Analytical geometry is the treatment of geometry within the context of, for example, the Cartesian coordinate system. This coordinate system uses equations to describe (i.e., define and represent) and manipulate numerically points, lines, planes, and geometric shapes (e.g., polygons) in, most often, the Euclidean plane (two-dimensional). As such, analytical geometry furnishes useful tools to analyze regional economic complexes and the geographic concentrations of many different and connected economic activities. These notions constitute the theme of this chapter.
