Author:Chaim Goodman-Strauss; The Geometry Center
Description: Studying symmetries called isometries, which preserve distances. Pattern and symmetry appear in virtually every human culture. Symmetry surrounds us, both in the natural world and in the world of human artifact... the arrangement of needles on a pine tree, the spokes of a hubcap, the vortices in the Mississipi River, the slats in a set of blinds... Mathematicians are relative newcomers to the symmetry game, but offer a useful, beautiful view. Definitions, Isometry Exercises, Combining symmetries. Homework uses The Geometer's Sketchpad and KaleidoTile. These pages were revised and edited by Heidi Burgiel. From Math 5337, Technology in the Geometry Classroom, The Geometry Center.
