NCERT Solutions for Class 9 Maths Chapter 6

First of all, Lines and Angles is a very important subject in Maths. This chapter will certainly provide the basics of Geometry to students of class 9. The chapter is essential for engineering. This is because Lines and Angles have a lot of utilization in constructions. Similarly, the chapter will help students to become an architect. Scientists also use Lines and Angles very much. Hence, it becomes clear that this chapter has uses in lots of fields.

Below is an explanation of the sub-units of this chapter:

6.1 Introduction – Here is an introduction to Lines and Angles. This part certainly gives a general idea.

6.2 Basic Terms and Definitions – This sub-unit contains terms and definitions. These terms are line-segment, ray, angles and its types. Furthermore, there are collinear and non-collinear points. Also, there are arms and vertex of the angles.

6.3 Intersecting Lines and Non-intersecting Lines – intersecting lines share exactly one point. In contrast, non-intersecting lines do not share this one exact point.

6.4 Pairs of Angles – There are some pairs of angles. These are complementary, supplementary, adjacent, and linear-pair of angles. Most noteworthy, there is a discussion of some relationships between these angles.

6.5 Parallel Lines and a Transversal – Parallel lines are always the same distance apart. Also, they never meet. Transversal is a line that intersects two or more lines at separate points.

6.6 Lines Parallel to the Same Line – Here two or more lines are parallel to the same line. These lines will be parallel to each other.

6.7Angle Sum Property of a Triangle – This means that the sum of the interior angles of a triangle is 180°. More properties are given.
