In general usage, symmetry most often refers to mirror or reflective symmetry; that is, a line (in 2-D) or plane (in 3-D ... All cyclic shapes have a mirror image that “spins the other way.” ...

This symmetry and regularity can seem mundane and almost invisible ... The problem with their approach was that their tile had to be disconnected; this would be like tiling the plane with shapes like ...

This course explores some visual aspects of mathematics. Topics are chosen from areas such as geometric constructions, tessellations of the plane, symmetry groups, Platonic and Archimedean solids, ...
