Concise Selina Solutions for Class 6 maths Chapter 24 Angles


In Euclidean geometry, an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle. Angles formed by two rays lie in the plane that contains the rays. The intersection of two planes also forms Angles. These are called dihedral angles. In geometry, an angle can be defined as the figure formed by two rays meeting at a common endpoint. Angles are measured in degrees, using a protractor.

Geometry is a branch of mathematics that deals with the study of shapes and their measurements. It also focuses on the relative configuration of the shapes and its spatial properties. We know that geometry is classified into 2D Geometry and 3D Geometry. Before dividing that, all the geometrical shapes are formed by points, lines, rays and plane surface. When the two lines or the rays converge at a common point, the measurement between the two lines is called an “Angle”.
