Exploring Nonconvex, Crossed and Degenerate Polygons
Contreras, Jose N.
Mathematics Teacher, v98 n2 p80 Sep 2004
An exploration of nonconvex, crossed, and degenerate polygons (NCCDPs) are described with the help of examples with pedagogical tips and recommendations that are found useful when teaching the mathematical process of extending geometric patterns to NCCDPs. The study concludes that investigating such extensions with interactive geometry software can be a natural activity as students investigate geometric relationships about NCCDPs.
