Summary

 there are two types of symmetry

  • line symmetry, which involves reflection
  • rotational symmetry, which involves rotation

the total order of symmetry of a shape is the sum of the number of lines of symmetry and the order of rotational symmetry of the figure.

Key Skills
  • draw the axes of symmetry of a shape
  • calculate the order of rotational symmetry of a shape

Vocabulary

 symmetry, axis of symmetry, order of rotational symmetry.
