Symmetry 4: Reflection (Flipping)
This is the basic "tile" shape of the tessellation on this page: it's a tropical reef fish. We make the tessellation is by repeating the tile and fitting all the tile's copies together. There are three ways that a tile can repeat: Translation, Reflection, and Rotation (Sliding, Flipping, and Turning). At right we see the second way: Reflection (Flipping). The shape of the fish repeats by reflecting...flipping...like a picture held up to a mirror. Also, there is a little translation (sliding): the fish moves a little down and a little left.
