Periodic 2

Here are two pictures made up of these shapes, or tiles. The one on the left is periodic - the pattern repeats in at least 2 directions. The one on the right is non-periodic, or aperiodic. The pattern of tiles does not repeat at all.

Can you see the way the tiles are arranged in both cases. The periodic tessellation should contain a fundamental cell. Can you see it? Press next page button below...
