                  MORE AbOUT PLANE SHAPES

                  Triangle, rectangle, square, circle and oval are plane shapes.                   INDIAHkkjr  2500

                  A plane shape can have sides and corners.                                                          Side

                  A corner of a plane figure is called its vertex. The plural of
                  vertex is vertices. A straight line forming a plane figure is                                     Vertex
                  called its side.

                  Let us know more about  plane shapes.
