Does any parallelogram tessellate

Answer 1

This is the fundamental, or primary, cell. Parallelograms will all tessellate. You can see that every part needed to make up the full foxes picture is contained in the parallelogram. All you need to do is to repeat them and you get the full tessellation. By joining similar points in a tessellation, it should usually be possible to work out the fundamental cell. In 2 motif tessellations it will contain both of them!
