              open figures


              Figures which have different starting and end points are called open figures. Look at
              the given figures.








              These all are open figures.

              closed figures

              Figures in which starting and end points coincide with each other are called closed

              figures. Look at the given figures.







              These all are closed figures.

              simple closed figures

              The closed figures or shapes which do not cross themselves at any point are called
              simple closed figures.

              Look at the given figures.







              These are simple closed figures.


              PoLyGons


              Simple closed figures which are made with only line segments are called polygons.
              Look at the given figures.






              These are polygons.

              types of Polygons


              A polygon is made with three or more line segments called sides. A polygon is identified
              as per the number of sides it has.
