                                       Chapter 10 – Symmetry and Pattern


               Sub-topic-1:- Symmetry in 2D shapes,alphabets,numbers


                    Symmetry - Symmetry most often refers to mirror or reflective symmetry; that is,
                      a line (in 2-D) or plane (in 3-D) can be drawn through an object such that the two
                      halves are mirror images of each other.

                    Symmetry is something that we observe in many places in our daily lives without
                      even noticing it. It is easily noticeable in various arts, buildings, and monuments.
                      Nature uses symmetry to make things beautiful. For example, consider the
                      pictures of the butterfly and the leaf .
