|Geometry from the Land of the Incas
Description:A Peruvian site with Euclidean geometry problems involving circles and triangles, with proofs, animation and sound: Poncelet, Napoleon, Eyeball, Steiner, Carnot, Sangaku, Morley, Langley and the Butterfly Theorem. You can also investigate Inca Geometry (Cuzco, Machu Picchu, Incan Quipu, Nazca Lines, Lord of Sipan); and quotes from Descartes, Galileo, Newton, Pappus, Plato, Poincaré, Voltaire, and try some quizzes.
|Math is Fun: Geometry
Description:Excellent site for exploring geometry. It offers easy to understand explanations and visuals with work using computer simulations where students can play with geometric figures, use math tools, and develop a hands-on understanding of what they have read.
Description:Why study non-Euclidian Geometry? This site provides the answers, plus the java script tools for students to see what they are learning! Interactive.
|Paper Models of Polyhedra
Description:Download the polyhedra graphics, print them on cardstock and then cut, fold, and glue to make your own models. The site includes some construction advice. It looks to me if you resized these graphic files and then traced them on origami paper you could make lovely ornaments.
|The Pi Page
Description:This website contains free graphics, animated GIFs, streaming video, lesson plans, links, and other resources about the Platonic solids.
