Polygonally → It is formed from "poly-" (from Greek "polus", meaning many) and "gon" (from Greek "gonia", meaning angle) and the suffix "-ally" (meaning in a manner). The word "polygonally" refers to something that is done in a manner relating to many angles, as polygons have multiple angles.
Think of 'many' ('poly-') angles ('gon') to remember that 'polygonally' describes something related to shapes with multiple angles.
