2.2  Symmetry


                  2.2  Symmetry





                We are going to …


                •  explore the symmetry in triangles
                •  explore the symmetry in patterns

                •  create patterns with lines of symmetry.





              Symmetry is all around you in nature and in art and design. In
              this section you will learn how to create symmetrical patterns.           line of symmetry

              Learning about symmetry helps you to notice similarity,                   symmetrical

              difference and balance, which is important to all parts of
               mathematics.
