Why Are NCERT Solutions For Class 9 Maths Important?
Mathematics is usually seen as a very challenging subject among students. In reality, maths is not tough in nature. The difference lies in the approach of studying and dealing with problems. All you need is a proper understanding of the subjects and regular practice.
The most important part is to solve the problems on your own rather than to just glance through the steps. Negligence at the initial stage may turn into fear. So, don’t give it a chance to hijack you. If you practice and follow the right approach you will love the subject. This habit will not only help you ace Class 9 final exams but will also help you to face the Class 10 Maths exam with confidence.
In this process of understanding the concepts and solving problems, the NCERT Grade 9 Maths solutions will help you a lot. Solving the exercise will help you identify your mistakes and to improve upon them.

NCERT Class 9 Maths Chapter Description
Let’s look at all the chapters within the Std 9 Maths textbook, in brief, to get an idea about what to expect from them. For each chapter, the answers are also linked so you can directly download them and start studying as well.
NCERT Solutions For Class 9 Maths: Chapter 1 Number Systems
If we want to measure our height, we would use feet or meters. If we want to calculate values or measure objects in a very exact manner, we cannot use natural numbers. We have to use special types of numbers, such as rational numbers, irrational numbers, and integers. This chapter helps you understand these different kinds of numbers and how to use them to solve problems.

NCERT Solutions For Class 9 Maths: Chapter 2 Polynomials
After understanding coefficients and variables, students learn polynomials, which are terms that are linked together using addition or subtraction. Let’s understand polynomials using this expression – “2x – 3y + a” where the value of x is unknown, and y also symbolizes an unknown number. Some are constant (does not change), others are variable (changes or varies with the situation).

NCERT Solutions For Class 9 Maths: Chapter 3 Coordinate Geometry
If you take your house as the center (a dot), then you can start plotting different paths, to your nearest neighbors, a grocery store around you, etc. If you define your house’s coordinates as (0,0), then similarly, you can plot the nearby objects with ease and measure distances between buildings. This concept is called “Coordinate Geometry”. It helps us to make graphs, which later on help in understanding complex algebra in later chapters. The concepts within the chapter include the cartesian plane, x-axis and y-axis, origin, quadrants, and abscissa.

NCERT Solutions For Class 9 Maths: Chapter 4 Linear Equations In Two Variables
Linear equations with two variables allow us to do interesting things with them. We can learn how to find the values of variables from these sorts of equations. For instance, if apples and oranges are two variables x and y. If the given equation is x+y = 20, we can determine the total value of both apples and oranges, but not individual values.

NCERT Solutions For Class 9 Maths: Chapter 5 Introduction To Euclid’s Geometry
The word Geometry is formed of two greek words “Geo” and “Metron” which means Earth and to measure. The man who gave the earth its first primer on geometry was Euclid, whose work “Elements” from 325 B.C. is still used today.
In this chapter, we learn about some basic shapes and terms within geometry, and also have a deeper look into axioms (definitions), postulates (laws), and theorems. These are some building blocks of geometry that help us understand more complex geometry that will come in later chapters.

NCERT Solutions For Class 9 Maths: Chapter 6 Line And Angles
We begin studying geometry with some basic elements of geometry such as points, lines, and angles. For instance, two separate points at any place can form a line, and when two lines intersect at a point or emerge from a single point, they form an angle. We see lines and angles everywhere around us: in all buildings, objects, and other complex structures. Learning these concepts will help you form a strong understanding of geometry.

NCERT Solutions For Class 9 Maths: Chapter 7 Triangles
In the previous chapter, we talked about two points forming a line. In this chapter, we explore how connecting any 3 points form a triangle. Depending on the position of those 3 points, triangles can have different angles within them that help us identify different types of triangles. By understanding these basics, students will be able to learn some theorems associated with triangles in this chapter.

NCERT Solutions For Class 9 Maths: Chapter 8 Quadrilaterals
After learning about structures formed by any 2 points (lines) and 3 points (triangles), we will learn about quadrilaterals, which are structures formed by connecting any 4 points. The chapter goes further into different types of quadrilaterals such as trapeziums, parallelograms, squares, rectangles, rhombuses, and kites. Learning about these different types of quadrilaterals allows us to understand the theorems associated with them and widen our understanding of geometry.

NCERT Solutions For Class 9 Maths: Chapter 9 Areas Of Parallelograms And Triangles
Combining our understanding of parallelograms and triangles from previous chapters, this chapter studies the relationship between both of these structures and the area they occupy. The majority of the chapter is about several theorems formed on the basis of these structures and is necessary for learning about more complex structures later on in geometry.

NCERT Solutions For Class 9 Maths: Chapter 10 Circles
After learning about lines and the shapes formed by using lines, we come to circles – some of the most common shapes seen around us in coins, dishes, wheels, and even the sun. We learn how to identify circles in the world of geometry and we understand a very commonly used irrational number – Pi (π). In this chapter, we also understand how we can use more symmetrical shapes and lines with circles and understand how to calculate their area with the help of Pi.

NCERT Solutions For Class 9 Maths: Chapter 11 Constructions
In this chapter, students get a chance to apply the knowledge of different shapes to construct different types of triangles using several different rules and some common tools used for geometry. By the end of this chapter, students will get a better understanding of how to construct shapes using theorems and rules learned in the earlier chapters.

NCERT Solutions For Class 9 Maths: Chapter 12 Heron’s Formula
Geometry is useful for so many things. One of them is finding areas of shapes. While we have understood how to determine the area of circles through Pi and so on, we will explore how Heron’s formula can help us find the area of triangles and other quadrilaterals by dividing them into triangles.

NCERT Solutions For Class 9 Maths: Chapter 13 Surface Areas And Volumes
We learned how to determine areas in a two dimensional (2-D) manner in earlier chapters. In this one, we delve into the 3-D aspect of geometry and determine the surface area of cuboids and cylinders. Simple formulas and application of geometrical concepts can help in understanding this and also how to determine the volume of such shapes.

Maths NCERT Solutions For Class 9: Chapter 14 Statistics
After studying Geometry, we explore another critical field in mathematics that is utilized in economics, business, and taken into account before any crucial decision is taken – Statistics. In Statistics, we collect data and learn how to represent it in ways that are understandable easily in a visual manner. We also learn how to determine the mean, median, and mode of a data set, and frequency distribution of data.

NCERT Solutions For Class 9 Maths: Chapter 15 Probability
Is it possible to predict the future? Not really, but it is possible to mathematically predict the likelihood of an event occurring, which is known as probability. Through the understanding of basic formulas and some interesting problems, students will be able to determine probability in a mathematical way. It is an important chapter that will be more useful as you explore maths in higher education.
