                           (e)  A _______ has no sides and corners.


                    Creating Shapes through Paper Folding and Paper Cutting


                    Let’s learn how to form diff erent shapes by paper folding and paper cu   ng.


                    Creating Shapes through Paper Folding


                    Let’s make various shapes by paper folding, and count the number of sides and

                    corners.

                    Step 1:  Fold a big square sheet of paper
                              as shown.









                    Step 2:  You will obtain the shape of a
                              rectangle. Count its sides and

                              corners.






                    Step 3:  Fold it again as shown. You will
                              obtain the shape of a square.

                              Count the number of sides and
                              corners.


                    Step 4:  Fold it again to obtain the shape

                              of a triangle. Count the number
                              of sides and corners.





                    In this way, we can fold a paper to obtain diff erent shapes.

                    Let’s make various shapes by paper cu   ng, and count the number of sides and
                    corners.
