A modular pentagonal star, whose creator is unknown, and a modular decagonal star designed by Tomoko Fuse will be folded using five and ten pieces of square paper, respectively. Angle measures of the decagonal star will be calculated to show how well the modular pieces fit together. Does each piece contribute exactly 36° to form a 360° circle? Participants will calculate angle measures in two different ways: by hand using high school mathematics, and on GeoGebra, a web-based graphing tool.
