              Use  a  scale  to  measure  the  distance  between  the  India  Gate  and  the  Red  Fort  shown
              below.




                                                       Scale: 1 cm = 750 m



              In the above picture, the distance between the India Gate and the Red Fort is 8 cm.
              The  scale  is  1  cm  =  750  m.  So,  the  actual  distance  between  the  India  Gate  and  the  Red
              Fort is 8 × 750 m = 6000 m = 6 km.

              Keys: The keys tell us the meaning of the different symbols used in the map.
              Look at the following map. It shows different places using different symbols.

                                                                       S
              directions

              A symbol like a compass is used to show the directions on a map. Look at                         N
              the given compass.

              We can see that the upper part shows ‘N’, which means the ‘North direction’,  W                         E
              the lower part shows ‘S’ meaning the ‘South direction’, the left part indicates
              ‘W’,  which  means  the  ‘West  direction’  and  the  right  part  shows  ‘E’,  which            S
              means the ‘East direction’.
              North, South, East and West are the primary directions.                            North (N)

              Now study the diagram shown alongside.                                    North-West           North-East
                                                                                          (NW)                  (NE)
                  Š The  direction  between  north  and  east  is  called  the
                  north-east (NE) direction.                                         West (W)                    East (E)
                  Š The  direction  between  north  and  west  is  called  the         South-West
                  north-west (NW) direction.                                              (SW)              South-East

                  Š The  direction  between  south  and  west  is  called  the                  South (S)     (SE)
                  south-west (SW) direction.
                  Š The direction between south and east is called the south-east (SE) direction.
