3.  Unfold it. With the help of a ruler and a pencil, draw                             line of

                   a straight line along the crease formed. This is the line                        symmetry
                   of symmetry of the rectangular sheet.

              4.  Fold the same sheet along the shorter side in such a
                   way that the two halves coincide.


              5.  Unfold it and draw the line of symmetry along the
                   crease formed.





            Can you get a line of symmetry by folding the rectangle along the diagonals?

            Now perform this activity to find the lines of symmetry of a square and complete the
            given table.

                                                    Symmetric along              Lines of
                                   Shape
                                                        diagonals              symmetry
