NUMB3RS - Season 3 - "Burn Rate" - Regular Polygon Centroids

Activity Overview

In "Burn Rate," mail bombs kill a series of seemingly unrelated people. Don asks Charlie to help uncover the source and the link that connects the people. Don's team has determined the locations where the letter bombs were mailed, where the components were bought, etc. Using geo-profiling, Charlie is able to find the likely starting point where the bomber set out to buy his bomb materials.
Students will do their own geo-profiling by finding the centroid of regular polygons.
