              Basic Geometrical concepts


              The word ‘Geometry’ is derived from the                          Knowledge Desk

              Greek word 'geo' meaning 'Earth' and 'metria'
              meaning 'measurement'. Let us learn about                                The  famous ancient  Greek

              point

              A point is represented by a tiny dot (.). A dot made with a sharp pencil can show a

              point.

              A point shows an exact position and has no length, width or thickness. Points                P       Q
              are denoted by capital letters like A, B, C, D, etc.                                         •       •

              In the figure, P, Q and R are points.                                                               • R
