## Chapter 1: Number Systems

The numeral or number system is the combination of natural, integers, rational, irrational, and real numbers. This lesson covers the entire concepts of the numeral system and its types, representation on the number line, laws of rational exponents, and integral powers. To simplify the concept of number systems, the technique of portraying numbers on a number line using certain rules and symbols is known as a** ****number system**. A **number line** is a straight-line representation of integers with a set spacing between them. The Number System is used to do mathematical computations ranging from intricate scientific calculations to calculate how many chocolates are left in the box.

The major topics covered in Number systems chapter in Class 9 are Representation of natural numbers, integers, rational numbers on the number line, Rational numbers as recurring/ terminating decimals and Operations on real numbers. Some topics which have great importance in further chapters of Class 9 are Rationalization of real numbers and Laws of exponents for real numbers

**Important rules that are used in CBSE Class 9 Maths Chapter 1- Number Systems are,**

- √ab = √a × √b
- √(a/b)= √a/√b
- (√a + √b) × (√a – √b) = a−b
- (a + √b) × (a − √b) = a
^{2}−b- (√a+√b)
^{2}=a^{2}+ 2√ab +b- a
^{p}× b^{q }= (ab)^{p+q}- (a
^{p})^{q}= a^{pq}- a
^{p}/ a^{q }= (a)^{p-q}- a

The coefficients involve operations such as subtraction, addition, non-negative integer variable exponents, and multiplication. Both **algebraic expression** and polynomials in mathematics are made up of variables and constants, as well as arithmetic operations. The sole difference is that algebraic expressions include irrational numbers in their powers.

Topics covered in Class 9 Polynomial Chapters are the basics of polynomial in one variable (including the Coefficients of a polynomial, terms of a polynomial and zero polynomial), Degree of a polynomial and Types of Polynomials-Monomials, binomials, trinomials. Some important topics covered in this chapter are Factors and multiples, Zeros of a polynomial, and Factorization using the Factor Theorem.

**Here is the list of the important theorems learned in CBSE Class 9 Maths Chapter 2- Polynomials,**

Remainder Theorem:If p(x) has the degree greater than or equal to 1 and p(x) when divided by the linear polynomial x – a will give the remainder as p(a).Factor Theorem:x – a will be the factor of the polynomial p(x), whenever p(a) = 0. The vice-versa also holds true every time.

## Chapter 3: Coordinate Geometry

**Coordinate geometry** is a part of geometry where the position of the points on the plane is described with the help of an ordered pair of numbers called **coordinates**.

Coordinate geometry is important because it connects geometry with **algebra **using line graphs and curves. Because it allows us to find points on any plane, coordinate geometry is helpful in mathematics. It is also used in trigonometry, calculus, and other fields. Learn about the cartesian system, coordinate points, how to plot points on coordinate axes, quadrants with signs, and other concepts in coordinate geometry.

**Important conclusions from CBSE Class 9 Maths Chapter 3- Coordinate Geometry are,**

- The horizontal line is known as the
x-axisand the vertical line is called they-axis.- The coordinates of a point are in the form of (+, +) in the first quadrant, (–, +) in the second quadrant, (–, –) in the third quadrant, and (+, –) in the fourth quadrant; where + and – denotes the positive and the negative real number respectively.
- The coordinates of the origin are (0, 0) and thereby it gets up to move in the positive and negative numbers.

## Chapter 5: Introduction to Euclid’s Geometry

**Euclidean geometry **is the branch of geometry that deals with the study of geometrical shapes and figures based on different axioms and theorems. This study provides a brief explanation for flat surfaces. This chapter is the introduction to Euclid for Class 9 students.

This chapter is all about Euclid’s method of formalizing observed phenomena into rigorous Mathematics with definitions, axioms, postulates and theorems. Also includes the five postulates of Euclid, Equivalent versions of the fifth postulate, and a Representation of the relationship between axiom and theorem.

**Here are the important rules from CBSE Class 9 Maths Chapter 5- Introduction to Euclid’s Geometry,**

Axioms:The basic facts which are taken for granted without proof are called axioms. Some of Euclid’s axioms are:

- Things which are equal to the same thing are equal to one another.
- If equals are added to equals, the wholes are equal.
- If equals are subtracted from equals, the remainders are equal.
- Things which coincide with one another are equal to one another.
- The whole is greater than the part.
Postulates:Axioms are the general statements, postulates are the axioms relating to a particular field. Euclid’s five postulates are.

- A straight line may be drawn from anyone point to any other point.
- A terminated line can be produced indefinitely.
- A circle can be drawn with any center and any radius.
- All right angles are equal to one another.
- 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 angles are less than two right angles.

## Chapter 6: Lines and Angles

In geometry, **Lines and Angles** are defined as figures that are made up of infinite points extending indefinitely in both directions. Lines are straight and have length and breadth, while an angle is a figure from which two rays emerge from a common point.

To define it in simpler words, a line is defined as a row of closely spaced dots that spans in two directions indefinitely. It just has one dimension, which is its length. A line can be represented by a horizontal mark written on a sheet of paper. An angle is a figure formed by two rays that intersect at a shared terminus. A protractor is used to measure them in degrees. Lines and angles are present in all geometry forms.

This chapter majorly includes the basics of Lines and Angles, and Types of angles. Also include important properties and theorems like the Angle sum property, etc.

**Important definitions from CBSE Class 9 Maths Chapter 6- Lines and Angles are,**

Acute angle:An acute angle measures between 0° and 90°.Right angle:A right angle is exactly equal to 90°.Obtuse angle:An angle greater than 90° but less than 180°.Straight angle:A straight angle is equal to 180°.Reflex angle:An angle that is greater than 180° but less than 360° is called a reflex angle.Complementary angles:Two angles whose sum is 90° are called complementary angles. Let one angle be x, then its complementary angle is (90°−x).Supplementary angles:Two angles whose sum is 180° are called supplementary angles. Let one angle be x, then its supplementary angle is (180°−x).Adjacent angles:Two angles are Adjacent when they have a common side and a common vertex (corner point) and don’t overlap.Linear pair:A linear pair of angles is formed when two lines intersect. Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180°, so a linear pair of angles must add up to 180°.Vertically opposite angles:Vertically opposite angles are formed when two lines intersect each other at a point. Vertically opposite angles are always equal.

**Chapter 6 of CBSE Class 9 Maths Notes covers the following topics:**
