• The 3 by 3 lattice has 4 lines of symmetry and
rotational symmetry of order 4.
How might this help?
• Flips or Turns / Reflections or Rotations – are they
the same or different?
• Try shading 1 square only. What symmetries are
possible?
• Try shading 2, 3, 4.. squares only. What symmetries are now
possible?
• How helpful would this table be?
