Folding paper, doing geometry figures

chris cambré, Sirje Pihlap, 3 mars 2018

Katrien Cnudde and Machteld Pensaert of UC Leuven-Limburg created a workshop on doing geometry by folding paper. By folding an A4-sheet, you can create triangles, kites and other figures. More, you can explore properties, calculate angles and dimensions of the figures. This GGbook is a digital version of material of this workshop to assist you when folding. Because, don't just look at the applets, but do the folding yourself and learn geometry by doing!
