                          1.  Is the fish made by you symmetrical?

                         2.  How many lines of symmetry can you see in the fish?

                         3.  Name the steps in which you can see line(s) of symmetry.

                         4.  Mark the lines of symmetry in step 1 and count them.

                         5.  In which of the steps is the paper not symmetrical?

                         6.  List any 3 things around you that are not symmetrical.

                    Symmetry

                    In the paper folding activity discussed in the warm up, we see that a figure is said to
                    be symmetrical if it can be folded into two halves that fit exactly over one another.
                    The imaginary line that divides it into two equal halves is called the line of symmetry.

                    Let us find the line(s) of symmetry in the following steps.

                                     8                                1

                    As we can see in step 8, there is one line of symmetry, whereas in step 1, there is
                    more than one line of symmetry. A figure which does not have a line of symmetry is

                    called a non-symmetrical figure, for example:

                                                                                                                 133
