# Catching a Point within a Teragon

Catching a Point within a Teragon

This Demonstration presents a solution to the problem of determining if a chosen point of a two-dimensional plane, selected using the locator, is within the region bounded by a regular convex polygon whose edges are replaced with randomized Koch curves. This region is a self-similar fractal curve called a teragon [1]. The internal and external areas exchange colors as the point crosses the boundary.
