                Have you ever made a paper fan? It looks like                     . Now, let us turn the paper fan



                to see how turning it makes different angles.

                                                                                                                    1

                                                                                                              2

                Turn In A DIreCTIon

                 Anticlockwise             Clockwise  A turn in a direction  can be  either  clockwise  or


                                                      anticlockwise.

                                                      A clockwise turn is a movement in the same direction
                                                      as the hands of a clock, while an anticlockwise turn is a
                                                      movement in the opposite direction.




                Let us see the movement of a car in clockwise and anticlockwise directions.
