The numbers which can be represented in the form of p/q, where q ≠ o and p and q are integers are called rational numbers. Rational numbers are denoted by Q. If p and q are co-prime then the rational number is in its simplest form. All-natural numbers, whole numbers and integer are rational number. Equivalent rational numbers (or fractions) have same (equal) values when written in the simplest form. Rational number between two numbers x and y = x+y/2 .
There are infinitely many rational numbers between any two given rational numbers. The numbers which are not of the form of p/q, where q ≠ 0 and p and q are integers are called irrational numbers. For example: √2, √7, 𝛑 etc. Rational and irrational numbers together constitute are called real numbers. The collection of real numbers is denoted by R.

NCERT Solutions for Class 9 Maths Chapter 2 Polynomials
NCERT Solutions for Class 9 Maths Chapter 3 Coordinate Geometry
This chapter recaps your basics about algebraic expressions. Polynomial is a specific type of algebraic expression and so this chapter involves all the terminologies and various operations on it. Our video solutions will be an excellent resort for this chapter from CBSE Class 9 Maths.
A polynomialp(x) in one variable x is an algebraic expression in x of the form
p(x) = a_{n}x^{n} + a_{n-1}x^{n-1} + a_{n-2}x^{n-2 }+ ...... + a_{2}x^{2} + a_{1}x + a_{0}, where
a_{0,}a_{1, }a_{2.......}a_{n} are constants
x is a variable
a_{0,}a_{1, }a_{2.......}a_{n} are respectively the coefficients of x^{i}
Each of a_{n}x^{n} + a_{n-1}x^{n-1} + a_{n-2}x^{n-2 }+ ...... + a_{2}x^{2}, a_{1}x, a_{0 }with a_{n }≠ is called a term of a polynomial.
Division algorithm
If p(x) and g(x) are the two polynomials such that degree of p(x) ≥ degree of g(x) and g(x) ≠ 0, then we can find polynomials q(x) and r(x) such that:
p (x) = g(x) q(x) + r(x)
where, r(x) =0 or degree of r(x) < degree of g(x).
Remainder theorem
Let p(x) be any polynomial of degree greater than or equal to one and let a be any real number. If p(x) is divided by the linear polynomial (x – a), then remainder is p(a).
If the polynomial p(x) is divided by (x + a), the remainder is given by the value of p(-a).
Factor theorem
Let p(x) is a polynomial of degree n ≥ 1 and a is any real number such that p(a) = 0, then (x - a) is a factor of p(x).
Converse of factor theorem
Let p(x) is a polynomial of degree n ≥ 1 and a is any real number. If (x - a) is a factor of p(x), then .... p(a) = 0.
An algebraic identity is an algebraic equation which is true for all values of the variables occurring in it.
Some useful quadratic identities:
(x + y)^{2} = x^{2} + 2xy + y^{2}
(x - y)^{2} = x^{2} - 2xy + y^{2}
(x - y)(x + y) = x^{2} - y^{2}
(x + a)(x + b) = x^{2} + (a + b)x + ab
(x + y + z)^{2} = x^{2} + y^{2} + z^{2 }+ 2xy + 2yz + 2zx
Here x, y, z are variables and a, b are constants.
Some useful cubic identities:
(x + y)^{3} = x^{3} + y^{3} + 3xy(x + y)
(x - y)^{3} = x^{3} - y^{3} - 3xy(x - y)
x^{3} + y^{3} = (x + y)(x^{2} - xy + y^{2})
x^{3} - y^{3} = (x - y)(x^{2} + xy + y^{2})
x^{3} + y^{3} + z^{3} - 3xyz = (x + y + z)(x^{2} + y^{2}+ z^{2} - xy - yz - zx)
If x + y + z = 0 then x^{3} + y^{3} + z^{3} = 3xyz
Here, x, y and z are variables.

NCERT Solutions for Class 9 Maths Chapter 3 Coordinate Geometry
Thoroughly understand the concept of the Cartesian plane with TopperLearning’s class 9th maths ncert solutions Chapter 3 Coordinate Geometry. Learn to plot points in a Cartesian plane with our Maths textbook solutions. Our experts include crucial concept insights in these model answers to give you more information for conceptual clarity.
Two perpendicular number lines intersecting at point zero are called coordinate axes. The horizontal number line is the x-axis (denoted by X’OX) and the vertical one is the y-axis (denoted by Y’OY). The point of intersection of x-axis and y-axis is called origin and denoted by ‘O’.
Cartesian plane is a plane obtained by putting the coordinate axes perpendicular to each other in the plane. It is also called coordinate plane or xy plane. The x-coordinate of a point is its perpendicular distance from y-axis.The y-coordinate of a point is its perpendicular distance from x-axis.
The point where the x axis and the y axis intersect is represented by coordinate points (0, 0) and is called the origin. The abscissa of a point is the x-coordinate of the point. The ordinate of a point is the y-coordinate of the point. If the abscissa of a point is x and the ordinate of the point is y, then (x, y) are called the coordinates of the point. The axes divide the Cartesian plane into four parts called the quadrants (one fourth part), numbered I, II, III and IV anticlockwise from OX.
Sign of coordinates depicts the quadrant in which it lies. The coordinates of a point are of the form (+, +) in the first quadrant, (-, +) in the second quadrant, (-,-) in the third quadrant and (+,-) in the fourth quadrant.
The coordinates of a point on the x-axis are of the form (x, 0) and that of the point on y-axis are (0, y).

NCERT Solutions for Class 9 Maths Chapter 5 Introduction to Euclid’s Geometry
How to prove that two distinct lines can’t have more than one point in common? Find out by using our class 9th maths ncert solutions Chapter 5 Introduction to Euclid’s Geometry. Learn about Euclid’s five postulates. Revisit the relation between theorem and axiom by practising with TopperLearning’s chapter-specific solutions.
A point is that which has no part. A line is a breadthless length. The ends of a line are points.
A straight line is a line which lies evenly with the points on itself. A surface is that which has length and breadth only. The edges of a surface are lines. A plane surface is a surface which lies evenly with the straight lines on itself. Though Euclid defined a point, a line and a plane, but the definitions are not accepted by mathematicians. Therefore, these terms are taken as undefined.
An axiom is a statement accepted as true without proof, throughout Maths. A postulate is a statement accepted as true without proof, specifically in geometry.
Theorems are statements which are proved using definitions, axioms, previously proved statement and deductive reasoning.
Euclid’s 5 Postulates:
1. A straight line may be drawn from any one point to any other point.
2. A terminated line can be produced indefinitely.
1. A circle can be drawn with any centre and any radius.
2. All right angles are equal to one another.
3. If a straight line falling on two straight lines makes the interior angles on the same side of it taken together less than two right angles, then the two straight lines, if produced indefinitely, meet on that side on which the sum of angles is less than two right angles.This is known as the parallel postulate.
Textbook solutions for CBSE Class 9 Maths will be useful when you sit to revise your lessons for class tests or exams. Other than NCERT Maths solutions, our video lessons, chapter notes and online practice tests will help you to understand theorems and postulates.

What is a Circle?
A circle is a collection (set) of all those points in a plane, each one of which is at a constant distance from a fixed point in the plane.
The fixed point is called the centre and the constant distance is called the radius of the circle.
Division of a plane using circle
A circle divides the plane on which it lies into three parts: inside the circle, the circle and outside the circle.
All the points lying inside a circle are called its interior points and all those points which lie outside the circle are called its exterior points.
The collection (set) of all interior points of a circle is called the interior of the circle while the collection (set) of all exterior points of a circle is called the exterior of the circle.
Arc of the circle
A (continuous) part of a circle is called an arc of the circle. The arc of a circle is denoted by the symbol ‘⌒’.
When an arc is formed, it divides the circle into two pieces (between the points A and B), the smaller one and the longer one. The smaller one is called the minor arc of the circle, and the greater one is called the major arc of the circle.

NCERT Solutions for Class 9 Maths Chapter 11 Surface Areas and Volumes
Revise the most important concepts in the chapter with class 9 maths solutions Chapter 11 Surface Areas and Volumes. In this chapter, TopperLearning gives you access to some of the best textbook solutions to understand the surface area of objects and spaces using the given data. Practise calculating the lateral surface area of a cubical box or the CSA of a given cylindrical pipe with our solutions.
If l, b, h denote respectively the length, breadth and height of a cuboid, then:
Lateral surface area or Area of four walls = 2(ℓ + b) h
Total surface area = 2(ℓb + bh + hℓ)
Volume = ℓ × b × h
Diagonal of a cuboid =
If the length of each edge of a cube is 'a' units, then:
Lateral surface area = 4 x (edge)^{2}
Total surface area = 6 x (edge)^{²}
Volume = (edge)^{3}
Diagonal of a cube = √3 x edge
If r and h respectively denote the radius of the base and the height of a right circular cylinder, then:
Area of each end or Base area = 𝜋r²
Area of curved surface or lateral surface area = perimeter of the base x height = 2𝜋rh
Total surface area (including both ends) = 2𝜋rh + 2𝜋r² = 2𝜋r (h + r)
Volume = Area of the base x height = 𝜋r²h

NCERT Solutions for Class 9 Maths Chapter 12 Statistics
How is data collected? What are the ways to present data? Discover the answers for these important questions in our class 9 maths solutions Chapter 12 Statistics. Practise the presentation of data in the form of histograms and bar graphs with our model answers for questions in the NCERT book.
A measure of central tendency tries to estimate the central value which represents the entire data.
The three measures of central tendency for ungrouped data are mean, mode and median.
The mean value of a variable is defined as the sum of all the values of the variable divided by the number of values.
If x_{1}, x_{2}, x_{3} .... , x_{n} are n values of a variable X, then the arithmetic mean of these values is given by:
If a variate X takes values x_{1}, x_{2}, x_{3}.... , x_{n} with corresponding frequencies f_{1}, f_{2}, f_{3},... fn respectively, then arithmetic mean of these values is given by
Median is the value of middle most observation(s).
The median is calculated only after arranging the data in ascending order or descending order.
Median =
Mode of a statistical data is the value of that variate which has the maximum frequency.
The variate corresponding to the highest frequency is to be taken as the mode and not the frequency.
The disadvantage of arithmetic mean is that it is affected by extreme values.
The disadvantage of mode is that it is not uniquely defined in many cases.
At TopperLearning, you can access our online NCERT textbook solutions for Class 9 Maths to revise mean, mode and median calculations. The chapter solutions also show the accurate way to construct a frequency distribution table according to the given information.
