Have you ever tried tessellating capital letters? Have a look at these examples and then try some for yourself.
How many different shapes can you make by putting four right- angled isosceles triangles together?
Use the clues about the symmetrical properties of these letters to place them on the grid.
Can you make the green spot travel through the tube by moving the yellow spot? Could you draw a tube that both spots would follow?
