                                       A  closed  figure  bounded  by  four
                                       equal line segments                                   4                    4

                                       Every square is a rectangle but every rectangle is not a square.

                    SquARe CoRneRS

                    One day, Meera was helping her dad arrange photo frames on

                    the wall. She noticed that the corners of the frames looked neat
                    and sharp. Her dad smiled and said, ‘Those are called square
                    corners!’ Meera got excited and started looking for more square
                    corners around her.

                    You can take a pair of straws and join them at one end. Then,
                    pull them apart from the other end as follows:
                         1.   Less than a Square Corner: The straw is slightly

                              lifted, creating a narrow gap. This is a less than                       Less than a square
                              square corner.                                                                  corner

                         2.   Square Corner: The straw is bent into an L shape.
                              This is a square corner.
                                                                                                          Square corner

                         3.   More  than  a  Square  Corner: The  straws  are
                              positioned wide apart, creating a wide gap. This is
                                                                                                           More than a
                              more than a square corner.                                                  square corner

                                                                                                                 129
                                                                                                    Geometry
