                    4.  Take  a  square  dotted  paper  and  draw different  polygons  with  3,  4,  5  and  6  sides.
                        Identify which polygon has 1 right angle, 2 right angles and 3 or more right angles.

                  5.  State  whether  the  following  statements  are  true or  false. Correct  the  false
                        statements.

                Do you know about Big Ben?

                Big  Ben is a famous clock  tower in London,
                England. Look  at  its  picture  alongside.  What
                shape does it remind you of? The Big Ben clock
                reminds us of the shape of a circle.

                You  can see  many  objects  which have the
                shape  of a circle.  Look  at  these  objects and
                observe their shapes.

                                                                                                       Tips

                The shape of each object represents a circle. A circle
                is a simple closed curve.                                            The word “circle” has its origins
                                                                                     in  the  Latin  word “circulus,”
                                                                                     which means a circular figure
                                                                                     or a small ring.
