The Symmetrical Patch

For the past couple of weeks, on my patch walks, I’ve been symmetry spotting.
To see if something is symmetrical: Pick it upTransform it (rotate, scale, reflect, flip etc)Put it down againIf it looks the same as before the transformation it’s symmetrical Popular items for this kind of transformation are spoons, static caravans and grandparents.

The most obvious kind of symmetry is reflectional (or bilateral).  An object has reflectional symmetry if there is a line going through it which divides it into two pieces which are mirror images of each other. There are several other kinds, however, and it's flippin' well everywhere.
