Shape and Space in Geometry

 Annenberg/CPB Examples:


The Annenberg/CPB site goes on to explain some very elementary notions of symmetry for the benefit of elementary-school teachers.

Here are some additional examples, following the above definition, of more traditional quilt blocks, with their traditional names:

Actually, a great deal more can be said about quilt geometry.
