Definition of Lines and Angles
We already know that lines and angles are the base shape of geometry and the knowledge of these helps us to better understand the concept of geometry. The basic definition of lines and angles is that the lines are 1-D figures that can be extended infinitely in the opposite direction, whereas an Angle is defined as the degree of mouth open when two lines intersect. If the wide space between the two intersecting lines is more then the angle between them is more.
These concepts are highly used to define various terms and are very helpful for students to study Geometry. Now let’s learn about them in detail.
Lines and Angles
Lines and Angles are the basic terms used in the Geometry. They provide a base for understanding all the concepts of geometry. We define a line as a 1-D figure which can be extended to infinity in opposite directions, whereas an angle is defined as the opening created by joining two or more lines. An angle is measured in degrees or in radians depending on the concept of the problem.
All the geometrical figures have lines and angles and having an understanding of them helps us to better understand the world of Geometry. In this article, we will learn about lines, angles, their types, properties, and others in detail.
