                Line of Symmetry

                Some figures have one line of symmetry, and some figures may have more than one

                line of symmetry. These shapes have more than one line of symmetry.

                          Two lines of symmetry Three lines of symmetry  Four lines of symmetry Many lines of symmetry
                example. Draw the line (or lines) of symmetry.

                    1.   Make a symmetrical design by folding and cutting paper.
                          Step 1.  Take a piece of paper                  Step 2.  Draw a curve forming

                                and fold it in half.                             a part of a leaf.

                          Step 3.  Cut the  folded  paper                 Step 4.  Unfold the paper you
                                 along the lines you                             have cut out.
                                 have drawn.

                        You will find that you have made a leaf. Decorate it using a pattern.

                    2.   Now take another piece of paper and fold it twice. Then cut and unfold it to make
                        a beautiful design.
