Line of symmetry

Today i am  teaching types of symmetry.

Types of symmetry
           
                        1. Line of symmetry
                        2.Mirror of symmetry
                        3.Rotational symmetry.

1.Line of symmetry
                     
                       When  a line  divides a given  figure into  two equal  halves such that  The left and right halves matchesexactly then we say  that the  figure is symmetrical about the line.This line is called the line of symmetry or axis of symmetry.
