You will start your journey with Number Systems. The first chapter in the NCERT 9th class Maths book will deal with terminating and non-terminating decimals, rational numbers, square roots, powers and rational exponents and the Rationalization of Real numbers.
In Polynomials, you will learn the definitions of polynomials, coefficients, degrees etc. You will also come across the different types of polynomials like Linear, quadratic, binomials, trinomials, factor theorems, etc.
In Chapter 3 of the NCERT 9th class Maths book, you will be dealing with the concepts of the Cartesian plane, coordinates of a point in the XY plane, notations, abscissa and also, plotting a point in XY-plane.
Chapter 4 will introduce you to the equation in two variables of the type ax+by+c=0. In this chapter, you will solve questions related to linear equations and also, plot linear equations on a graph.
Chapter 5 will advance your knowledge in Geometry. Euclid's Geometry chapter will help you understand how common geometric shapes and terms are defined. It will also dive deep into the relationship between postulates, axioms and theorems.
Lines and Angles will help you understand a few theorems about parallel lines, transversals, interior angles etc., and how you can apply them to find proofs of different verification problems.
Chapter 7 in the NCERT 9th class Maths book will study about the congruency of triangles and the rules of congruency. It will also acquaint you with more properties of triangles and about the inequalities in a triangle.
In Quadrilaterals, you will learn about a few properties of quadrilaterals and theorems to help you with proofs in verification problems. It will also help you understand combinations of quadrilaterals and triangles.
This is an important chapter in the NCERT 9th class Maths book. In this chapter, you will learn about the concepts of the areas of Parallelograms and Triangles and solve problems to find out the area of a region, parallelograms and triangles.
In Circles, you will learn about chords, equal chords, the angle subtended by an arc of a circle, cyclic quadrilaterals and several important theorems related to circles, quadrilaterals and triangles.
In this chapter, you will learn about constructions of different angles using bisectors as well as the construction of triangles, all using a ruler and a compass.
Heron’s Formula chapter will extend your knowledge in relation to the area of a triangle. By using Heron’s Formula, you will be solving problems to find the area of triangles and quadrilaterals.
In the previous classes, you have dealt with mensuration of 2-D figures. Chapter 13 in the NCERT 9th class Maths book, you will dive into problems to find out the volume and surface area of 3-D objects like cuboid, cubes, cylinders, spheres, etc.
You have dealt with statistics in your previous classes. In this chapter, you will have to group data into tabular form and find the mean, mode and median. You will also have to draw data from histograms, pie charts or other visual representation of data.
The final chapter in the NCERT 9th class Maths book is based on finding the probability of favourable outcomes from a random event. In this chapter, you will be dealing with real-life problems, mostly related to cards and dice.
The Mathematics syllabus for Class 9 is quite vast. You will require a good plan to complete this syllabus thoroughly. You might even want to take the help of your friends and arrange for a group study. You can easily download the NCERT 9th Class Maths book PDF.
