**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)
