1. Do all shapes tessellate?
No, many shapes do not tessellate. All triangles and quadrilaterals tessellate. Regular pentagons and octagons do not tessellate.
2. How is the TOTAL order of symmetry calculated?
By adding together the number of axes of symmetry and the order of rotational symmetry.
3. Can a shape have an order of rotational symmetry of 0?
No. All shapes have an order of symmetry of at least 1 (This is a turn of 360°)
4. What is point symmetry?
Point symmetry is when a shape maps onto itself under a rotation of 180° (a half turn)
