                    ANGle

                    Sahil is playing with paper strips. He has created the following things:

                    Two strips are meeting at a point and forming an angle. Similarly, when two lines meet
                    at a point, they create an angle.
                    In the adjacent figure, rays OA and OB meet at point O. They form                                  A
                    an angle.

                    The rays forming an angle are called its arms, and the point where                        Arm
                    the arms meet is called its vertex.                                                  O     Angle       B

                    Here, OA and OB are the arms of angle AOB and O is the vertex.                     Vertex      Arm

                    Angle AOB is denoted as ∠AOB or ∠BOA or ∠O, where ‘∠’ is the symbol for an angle.

                                                                                                                 119
