NCERT Solutions for Class 9 Maths Chapter 6 Lines and Angles - PDF Download

NCERT solutions for class 9 maths chapter 6 Lines and Angles, focuses on the study of lines and angles. This chapter teaches the properties of angles formed by two lines that intersect and the properties of angles created by a line that intersects two parallel lines. A line that has a start and end is called a line segment, and a line that only has one end is called a ray. Basically, two rays coming from the same end makeup an angle, the arms of the angle are called rays, and the end of the angle is called the vertex.

It is essential to acquire a thorough knowledge of lines and angles for both academic and practical purposes. Students will learn the properties of the sum of the angles formed by these kinds of lines and more by completing the exercises in NCERT solutions for  class 9 maths chapter 6.

Important Topics covered in Chapter 6 - Lines and Angles

This NCERT solution for class 9 maths chapter 6 is based on the fundamental concepts of angles and their properties, as well as their sum. We have covered important topics of NCERT solutions for class 9 maths chapter 6 here.

6.1 Introduction - In chapter 5, you have learned that two points form a line. This chapter will provide you with information on the properties of the angles formed by the intersection of two lines, as well as those formed when a line is crossed at two or more parallel points. In addition, you will apply these properties to some statements in a logical way.

6.2 Basic Terms and Definitions - In this section, you’ll find the basics of straight lines and line segments, as well as definitions of angles. In addition, you will be introduced to the various types of angles, which have been extensively discussed in our NCERT solution for class 9 maths chapter 6.

6.3 Intersecting Lines and Non-intersecting Lines - Intersecting lines are defined when two lines intersect at one point, and non-intersected lines are defined when the lines do not intersect at one point. You can use the exercise questions provided in NCERT solutions to help you understand this concept.

6.4 Pair of Angles - In this part, you will learn about the following types of angles: Complementary angles, Supplementary angles, Interior angles, Linear pairs of angles, adjacent angles etc. Each pair of angles, with its axioms and their theorems, can be studied in detail in NCERT solutions for class 9 maths chapter 6.

6.5  Lines Parallel to the Same Line - If you have two lines that are parallel, then the third line should be parallel to them too. That is what you'll learn in this section. 

For detailed explanation, please refer to NCERT solution for class 9 maths chapter 6.

Important Theorems Covered In NCERT solutions for Class 9 Maths Chapter 6 - Lines and Angles

In this section you will learn about two fundamental Geometry theorems with a couple of examples. These theorems are:

1.  Theorem - If two lines intersect each other, then the vertically opposite angles are equal.

2. Theorem - Lines which are parallel to the same line are parallel to each other.
