                  The word Geometry is derived from the                                    The  famous ancient  Greek
                  Greek word 'geo' meaning 'Earth' and 'metria'                            mathematician,    Euclid   is

                  meaning 'measurement'. Let us study some                                 considered as the father of

                  basic geometrical concepts.

                  point

                  A point is represented by a tiny dot (.). A dot made by using a sharp pencil may be taken

                  as roughly representing a point.
                  A point shows an exact position and it is said to have no length, width or  P                        Q

                  thickness. Points are denoted by capital letters such as A, B, C, D, etc.                    •       •
                  Here, P, Q and R are points in the figure given alongside.                                          • R
