Coordinate Geometry Class 9 Chapter 3 Ex 3.2 NCERT Solutions

Coordinate Geometry Class 9 Exercise 3.2 focuses on identifying and plotting points correctly in all four quadrants. This exercise helps students understand how positive and negative values of x and y affect the position of a point on the plane.

These NCERT Maths Class 9 Coordinate Geometry Exercise 3.2 solutions explain each question in a simple manner so that students can practise confidently. By solving these problems, you can start recognizing patterns in quadrants and interpreting the location of points without confusion.

Class 9 Chapter 3 Coordinate Geometry Exercise 3.2 Solutions

Class 9 Chapter 3 Coordinate geometry Exercise 3.2 Questions focus on recognising coordinates and placing them in the correct quadrant. Students will practise describing point positions and strengthening their understanding of signs of x and y. Class 9 Chapter 3 Coordinate Geometry Exercise 3.2 Solutions are given here:

Question 1. Write the answer to each of the following questions.

(i) What is the name of the horizontal and vertical lines drawn to determine the position of any point in the Cartesian plane?

(ii) What is the name of each part of the plane formed by these two lines?

(iii) Write the name of the point where these two lines intersect.

Solution:

(i) The name of horizontal and vertical lines drawn to determine the position of any point in the Cartesian plane is the x-axis and the y-axis, respectively. (ii) The name of each part of the plane formed by these two lines, the x-axis and the y-axis, is quadrants. (iii) The point where these two lines intersect is called the origin.

Question 2. See Fig.3.14, and write the following.

i. The coordinates of B.

ii. The coordinates of C.

iii. The point identified by the coordinates (–3, –5).

iv. The point identified by the coordinates (2, – 4).

v. The abscissa of the point D.

vi. The ordinate of the point H.

vii. The coordinates of the point L.

viii. The coordinates of the point M.

Solution:

i. The coordinates of B are (−5, 2). ii. The coordinates of C are (5, −5). iii. The point identified by the coordinates (−3, −5) is E. iv. The point identified by the coordinates (2, −4) is G. v. Abscissa means x coordinate of point D. So, abscissa of point D is 6. vi. Ordinate means y coordinate of point H. So, the ordinate of point H is -3. vii. The coordinates of point L are (0, 5). viii. The coordinates of point M are (−3, 0).

How to Prepare NCERT Maths Class 9 Coordinate Geometry Exercise 3.2?

To practise coordinate geometry class 9 exercise 3.2 effectively, follow these tips:

• Learn quadrant rules:

• (+, +) → 1st quadrant

• (–, +) → 2nd quadrant

• (–, –) → 3rd quadrant

• (+, –) → 4th quadrant

• Memorise sign patterns as this will help you identify quadrant positions instantly without using a graph.

• Plot many random points on graph paper to get comfortable with sign-based positions.

• Understand points on axes, for example if x = 0 or y = 0, the point lies on the axis, not in a quadrant.

• Compare your reasoning with the PDF solutions to correct mistakes quickly.
