                          The table 5.1 shows a list of polygons and the number of sides corresponding to them.

                                                          Table 5.1: List of Polygons


                                             Number of Sides                    Polygon name
                                   3                                  Triangle
                                   4                                  Quadrilateral
                                   5                                  Pentagon
                                   6                                  Hexagon
                                   7                                  Heptagon
                                   8                                  Octagon
                                   9                                  Nonagon
                                   10                                 Decagon
                                   11                                 Undecagon
                                   12                                 Dodecagon




                                      Based on the sides  and angles the polygons  are  classified  as regular and irregular
                                      polygons.


                          Figure 5.1 shows the list of regular and irregular polygons.
