Topics Covered in Exercise 3.2 class 9 Mathematics Questions

Ex 3.2 discusses the important topic of the cartesian system and its related concepts. You can check the detailed explanations mentioned below.

1. Cartesian System - The Cartesian system describes a point’s location in a plane. In a cartesian system, a point is defined by reference to two perpendicular lines. The horizontal line in the X-axis is called XX’ and the vertical line is called YY’. 

2. Important Points

• Origin - The point of origin, denoted by the letter 'O', is the point where the vertical and horizontal lines intersect. Positive directions correspond to OX and OY, while negative directions correspond to OX' and OY'.

• Coordinate Axes and Quadrants - The plane is divided into four parts by the axes X and Y. The four quadrants of the plane are numbered as I, II, III, IV  anti-clockwise from OX. The Cartesian plane, also called coordinate plane or XY plane, is made up of these axes and quadrants. These axes are also referred to as coordinate axes.

• Points in Different Quadrants 

1. The first quadrant - coordinates of a point are of the form (+ , +) 

2. The second quadrant - coordinates of a point are of the form (–, +)

3. The third quadrant - coordinates of a point are of the form (–, –) 

4. The fourth quadrant - coordinates of a point are of the form (+, –) 

                        where ‘+’ denotes a positive real number and ‘–’ denotes a negative real number.

Frequently Asked Questions

Question 1. What is the cartesian plane in NCERT solutions class 9 maths chapter 3 ex 3.2?

Answer 1. The cartesian plane is also known as a two dimensional coordinate plane that is defined as the plane where the x-axis is perpendicular to the y-axis. This point is called the origin of the cartesian plane.

Question 2. What are the components of a Cartesian plane?

Answer 2. The cartesian plane is composed of three different components. These components are essential when attempting to locate a specific point on the plane or construct a graph for a function. Here, we provide a comprehensive list of the components of a Cartesian plane.

Origin -  Origin is defined as the point where the vertical and horizontal lines intersect. The coordinate points of origin, denoted by (o,o).

Axes - The axes are the horizontal and vertical lines that intersect to form the cartesian coordinate system. The horizontal line is the x-axis and the vertical line is the y-axis.

Quadrants - When the axes of x and y intersect, the cartesian plane divides into four parts called quadrants. These quadrants can be infinite.
