## NCERT Solutions forÂ Class 10 Maths

#### Chapter 1 – Real Numbers

In chapter 1 of class 10, students will explore real numbers and irrational numbers. The chapter starts with the Euclid’s Division Lemma which states that “Given positive integers a and b, there exist unique integers q and r satisfying a = bq + r, 0â‰¤r<b”. TheÂ Euclid’s Division algorithm is based on this lemma and is used to calculate the HCF of two positive integers. Then, the Fundamental Theorem of Arithmetic is defined which is used to find the LCM and HCF of two positive integers. After that the concept of irrational number, rational number and decimal expansion of rational number is explained with the help of theorem

#### Chapter 2 – Polynomials

In Polynomials chapter begins with the definition of degree of the polynomial, linear polynomial, quadratic polynomial and cubic polynomial. This chapter has total 4 exercises including the optional exercise. The exercise 2.1 includes the questions on finding the number of zeroes through graph. It requires the understanding of Geometrical Meaning of the Zeroes of a Polynomial. The exercise 2.2 is based on the Relationship between Zeroes and Coefficients of a Polynomial where students have to find the zeros of quadratic polynomial and in some of the questions they have to find the quadratic polynomial. In exercise 2.3, the concept of division algorithm is defined and students will find the questions related to it. The optional exercise i.2 2.4 consists the questions from all the concepts of chapter 2.

#### Chapter 3 – Pair of Linear Equations in Two Variables

This chapter explains the concept of “Pair of Linear Equations in Two Variables”. This chapter has total 7 exercises and in these exercises different methods of solving the pair of linear equations is described. The exercise 3.1 describes how to represent a situation algebraically and graphically. The exercise 3.2 explains the methods of solving the pair of linear equation through Graphical Method. Exercise 3.3, 3.4, 3.5, 3.6 describesÂ Algebraic Method, Elimination Method,Â Cross-Multiplication Method,Â Substitution Method respectively. The exercise 3.7 is optional exercise which contains all types of questions. Students must practice these exercise to master in the method of solving the linear equations.

#### Chapter 4 – Quadratic Equations

In this chapter students will get to know the standard form of writing a quadratic equation. Then this chapter will explain the method of solving the quadratic equation through factorisation method and completing the square method. Chapter ends with the topic on finding the nature of roots which states that, a quadratic equation axÂ² + bx + c = 0 has

- Two distinct real roots, if bÂ² – 4ac > 0
- Two equal roots, if bÂ² – 4ac = 0
- No real roots, ifÂ bÂ² – 4ac < 0

#### Chapter 5 – Arithmetic Progressions

This chapter introduces students to a new topic that isÂ Arithmetic Progression i.e AP. This chapter constitute of total 4 exercises. In exercise 5.1, students will find the questions related to representing a situation in form of AP, finding the first term and difference of an AP, finding out whether a series is AP or not. The exercise 5.2 includes the questions on finding out the nth term of an AP by using the following formula;

a_{nÂ }= a + (n-1) d

The next exercise i.e 5.3, contains the questions on finding the sum of first n terms of an AP. The last exercise include higher level questions based on AP to enhance students analytical and power solving skills.

#### Chapter 6 – Triangles

In chapter 6 of class 10 CBSE maths, students will study about those figures which have the same shape but not necessary the same size. The chapter starts with the concept of similar and congruent figure. It further explains the condition for similarity of two triangles and theorems related to the similarity of triangles. After that, the areas of similar triangles has been explained with a theorem. At the end of this chapter the Pythagoras Theorem and converse of Pythagoras Theorem is described.

#### Chapter 7 – Coordinate Geometry

In this chapter students will learn how to find the distance between two points whose coordinates are given, and to find the area of the triangle formed by three given points. Along with this students will also study how to find the coordinates of the point which divides a line segment joining two given points in a given ratio. For this students will get introduced to Distance Formula, Section Formula and Area of a Triangle in this chapter.

#### Chapter 8 – Introduction to Trigonometry

This chapter will introduce students to Trigonometry. They will study some ratios of a right triangle with respect to its acute angles, called trigonometric ratios of the angles. The chapter also defines the trigonometric ratios for angles of 0^{0} and 90^{0}. Further, students will also know how to calculate trigonometric ratios for some specific angles and establish some identities involving these ratios, called trigonometric identities.

#### Chapter 9 – Some Applications of Trigonometry

This chapter is the continuation of the previous chapter as here student will study the application of trigonometry. It is used in geography, navigation, construction of maps, determining the position of an island in relation to the longitudes and latitudes. In this chapter students will see how trigonometry is used for finding the heights and distances of various objects, without actually measuring them. They will get introduced to the term line of sight, angle of elevation, angle of depression.

#### Chapter 10 – Circles

In earlier classes students have studied about circle and various terms related to a circle like chord, segment, arc etc. In this chapter, students will study the different situations that arises when a circle and a line are given in a plane. So, they will get thorough with the concept of Tangent to a Circle and Number of Tangents from a Point on a Circle.

#### Chapter 11 – Constructions

In this chapter consist of total 2 exercises. Whatever students have learned about construction in earlier classes will also help them.

Method and steps for construction are explained and also some example are given to make it more clear to the students.

#### Chapter 12 – Areas Related to Circles

This chapter begins with the concepts of perimeter and area of a circle. Using this concept the chapter further explains, how to find the area of sector and segment of a circular region. Moreover, students will get to know how to find the areas of some combinations of plane figures involving circles or their parts.

#### Chapter 13 – Surface Areas and Volumes

In chapter 13, there are total 5 exercises. The first exercise consist the questions based on finding the surface area of an object formed by combining any two of the basic solids i.e cuboid, cone, cylinder, sphere and hemisphere. In exercise 13.2 questions are based on finding the volume of objects formed by combining any two of a cuboid, cone, cylinder, sphere and hemisphere. The exercise 13.3 deals with the questions in which solid is converted from one shape to another. The exercise 13.4 is based on finding the volume, curved surface area and total surface area of frustum of a cone. The last exercise is optional and has high level questions based on all the topics of this chapter.

#### Chapter 14 – Statistics

Here students will learn numerical representation of ungrouped data to grouped data and finding theÂ Mean, Mode and Median. Also the concept of cumulative frequency, cumulative frequency distribution and how to draw cumulative frequency curves will be explained.

#### Chapter 15 – Probability

The last chapter deals with the probability. The chapter starts with the theoretical approach of probability.
