                  MorE about PLanE ShaPES

                  A triangle, rectangle, square, circle and oval are plane                      INDIAHkkjr  2500

                  shapes. A plane shape can have sides and corners and they                                          Side

                  can be drawn on a piece of paper.

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

                  Let us learn more about  plane shapes.
