Coordinates Class 9 Maths NCERT Solutions

The NCERT Solutions Class 9 Maths Chapter 1 Coordinates cover every question from the new Ganita Manjari book. This is the first chapter of the 2026-27 syllabus. It teaches you how to locate a point on a plane using two numbers, and how to find the distance between two points.

• Exercises solved: Exercise Set 1.1, Exercise Set 1.2, and all 16 End-of-Chapter problems
• Main skills: plotting points, reading coordinates, and using the distance idea
• Why it matters: it builds the base for coordinate geometry in Class 10

These solutions are prepared by subject teachers, matched to the current 2026-27 NCERT, and checked step by step so a Class 9 student can follow each line.

What Does Class 9 Maths Chapter 1 Coordinates Cover?

The chapter starts with a simple idea. To fix any point in a room or on a map, you need two numbers. Chapter 1 turns this into the coordinate plane, with an x-axis and a y-axis that meet at the origin. You learn to write a point as (x, y), plot it, and read its position back. The NCERT Solutions Class 9 Maths Chapter 1 Coordinates then show how to find the distance between two points using the Baudhayana-Pythagoras rule.

Class 9 Maths Chapter 1 Coordinates Exercise-Wise Breakdown

The chapter has two exercise sets and one long End-of-Chapter set. The table below shows what each part asks, so you can plan your practice.

Common Mistakes Students Make in Coordinates

Most errors in this chapter come from small slips, not hard ideas. Fix these early and your marks stay safe.

• Reading the y-value first when plotting a point.
• Forgetting the sign, so a point lands in the wrong quarter of the plane.
• Skipping the square root at the end of a distance sum.

Sample Solved Question from Class 9 Maths Chapter 1

Here is one End-of-Chapter type question, solved step by step, so you can see the method.

Question: Find the distance between the points A(1, 2) and B(4, 6).

Step 1. Find the horizontal gap and the vertical gap. Here the x-gap is 4 - 1 = 3 and the y-gap is 6 - 2 = 4.

Step 2. Use the Baudhayana-Pythagoras rule. The distance is √3² + 4².

Step 3. Simplify inside the root: √9 + 16 = √25.

Final answer. The distance is 5 units.

How to Study Coordinates and Time Needed
