The various angles which are formed by the two rays are explained in Exercise 4.3. The two rays which form an angle are the arms or sides and the initial point, which is common, is called the vertex. The students, by solving problems using solutions designed by our faculty obtain a better knowledge of concepts which are covered here. For more information regarding solutions, the students can avail NCERT Solutions Class 6 Maths Chapter 4 Basic Geometrical Ideas Exercise 4.3 PDF, which are provided here.
