# RS Aggarwal Solutions for Class 6 Maths Chapter 13: Angles and Their Measurements

Angles have been a very important topic since early ages. Angles are of utter importance in fields of physics, engineering, architecture, carpentry etc. In RS Aggarwal Class 6 Chapter 13, we will study the basic concepts of angles, their types and how to measure them.

An angle can be defined as the figure formed by two rays meeting at a common endpoint. The common endpoint is known as the vertex of the angle. An unknown angle is represented by the Greek letter “ፀ” also known as theta. We will get to know various parts of the angles like arms, vertex etc., in this chapter.

Important topics like the use of angles and types of angles are also covered in this chapter. There are various types of angles like acute, obtuse, and right angles, and we will learn how to identify them and their properties. The concept of angle measurement is brilliantly covered in this textbook. The theory of angles is one of the essential principles of geometry. Although the principle of equality, numbers, and angle differences are significant in geometry, concepts like trigonometry focus on angle measurement. Topics like positive angles and negative angles are covered under the topic called rotation of the angle. The chapter has some exercises based on these concepts, and these vary in difficulty. Usually, the exercises in the starting are easy and gradually, the difficulty level increases.

If the student encounters any trouble solving an issue in the exercise, he/she can use the solutions found on the official website of the Aakash Institute. They use a step-by-step approach to help the students grasp the material and get excellent grades on the topic.
