Unit- Number Systems

1. Number System

Review of representation of natural numbers, integers, rational numbers on the number line. Rational numbers as recurring/ terminating decimals. Operations on real numbers.

  1. Examples of non-recurring/non-terminating decimals. Existence of non-rational numbers (irrational numbers) such as, \[\sqrt{2}\], \[\sqrt{3}\] and their representation on the number.

  2. Rationalization (with precise meaning) of real numbers of the type \[\frac{1}{a + b\sqrt{x}}\] and \[\frac{1}{\sqrt{x} +\sqrt{y}}\] and their combinations) where x and y are natural number and a and b are integers.

  3. Recall of laws of exponents with integral powers. Rational exponents with positive real bases (to be done by particular cases, allowing learner to arrive at the general laws.)


Unit-Algebra

2. Linear Equations in Two Variable

Recall of linear equations in one variable. Introduction to the equation in two variables. Focus on linear equations of the type ax+by+c=0. Explain that a linear equation in two variables has infinitely many solutions and justify their being written as ordered pairs of real numbers, plotting them and showing that they lie on a line. Graph of linear equations in two variables. Examples, problems from real life with algebraic and graphical solutions being done simultaneously


Unit-Coordinate Geometry

3. Coordinate Geometry

The Cartesian plane, coordinates of a point, names and terms associated with the coordinate plane, notations, plotting points in the plane.


Unit-Geometry

4. Lines and Angles

1. (Motivate) If a ray stands on a line, then the sum of the two adjacent angles so formed is 180˚ and the converse.

2. (Prove) If two lines intersect, vertically opposite angles are equal.

3. (Motivate) Results on corresponding angles, alternate angles, interior angles when a transversal intersects two parallel lines.

4. (Motivate) Lines which are parallel to a given line are parallel.

5. (Prove) The sum of the angles of a triangle is 180˚.

6. (Motivate) If a side of a triangle is produced, the exterior angle so formed is equal to the sum of the two interior opposite angles.


5. Triangles

1. (Motivate) Two triangles are congruent if any two sides and the included angle of one triangle is equal to any two sides and the included angle of the other triangle (SAS Congruence).

2. (Motivate) Two triangles are congruent if any two angles and the included side of one triangle is equal to any two angles and the included side of the other triangle (ASA Congruence).

3. (Motivate) Two triangles are congruent if the three sides of one triangle are equal to three sides of the other triangle (SSS Congruence).

4. (Motivate) Two right triangles are congruent if the hypotenuse and a side of one triangle are equal (respectively) to the hypotenuse and a side of the other triangle. (RHS Congruence)

5. (Prove) The angles opposite to equal sides of a triangle are equal.

6. (Motivate) The sides opposite to equal angles of a triangle are equal.

7. (Motivate) The sides opposite to equal angles of a triangle are equal.


Unit-Mensuration

6. Heron’s Formula

Area of a triangle using Heron's formula (without proof)


Unit-Statistics & Probability

7. Statistics

Introduction to Statistics: Collection of data, presentation of data — tabular form, ungrouped/ grouped, bar graphs, histograms

FAQs on CBSE Revised Syllabus for Class 9 Maths 2022-23

1. What are Polynomials? What are its types?

The term polynomial is a mixture of poly or many, and nomial which means terms. It is ideally an expression that is composed of exponents, variables, and constants. It is proved through equations like addition, multiplication, and subtraction. The monomial, polynomial, trinomial, and binomial is classified by determining the number of terms present in an equation. 


A monomial is an expression that includes one term which is non zero. Whereas a binomial is a polynomial variant containing two terms. It is seen that a binomial can be a product or sum of two or more monomials. A trinomial exactly includes three terms.

2. What are the properties of a triangle?

The following are some of the relevant properties of a triangle:

  • The sum of all the three angles present in a triangle must be equal to 180°.

  • The length of the third side should be lesser than the sum of the length of the other two sides of the same triangle. 

  • The side opposite the greatest angle is the longest side of all the three sides of a triangle.

  • Area of a triangle is calculated as half of the product of base and height.

  • The perimeter is calculated as the sum of all the three sides of a triangle.

3. What are quadrilaterals? Explain some types.

Quadrilateral in general refers to a closed figure that has four sides. The basic types of quadrilaterals are:

  1. Parallelogram: The opposite sides of this quadrilateral are parallel to each other.

  2. Rectangle: In this quadrilateral, all the sides are at right angles to each other

  3. Square: It is a quadrilateral that has all four sides of the same length.

  4. Rhombus: It is similar to parallelogram but has all four sides equal.

  5. Trapezium: It is a quadrilateral that has only one side parallel to each other while the other side is not parallel to each other.
