The figure on the left side of the line of symmetry is the same as the figure on the right
            side. In other words, one side of the figure will exactly fit over its other side. Such figures
            are called symmetrical figures.

            The lines of symmetry can be horizontal, vertical or both.

            Look at the given examples.











                      vertical                    horizontal                      vertical and horizontal






            Some figures can have more than two lines
            of symmetry.







            Some figures are not symmetrical.





                                                     EXERCISE 13.5


              1.  Draw the line(s) of symmetry, if any, for the following figures.

                  (a)                               (b)                            (c)






              2.  Complete the figures along their line of symmetry.





                  (a)                               (b)                            (c)






                  (d)                               (e)                            (f)






                                                                                                                 175
