Coordinates Section-by-Section Overview
The chapter moves in a clear order, from the basic idea of a point to real-world grids. The table below maps each section to what you will learn.
| Section | Topic | What you will learn |
|---|---|---|
| Why We Need Coordinates | Fixing a position | Why two numbers are needed to locate a point, told through its history in Bhaarat |
| The 2-D Cartesian System | Axes and origin | Writing a point as (x, y), then plotting and reading it back |
| The Four Quadrants | Signs and order | The sign pattern in each quadrant and why order matters in a pair |
| Distance Between Two Points | Distance formula | Using the Baudhayana-Pythagoras rule to measure the gap |
| Midpoints and Handy Tools | Midpoint and collinearity | Finding a midpoint and checking if three points lie on a line |
| Coordinates in the Real World | Maps and screens | How grids run GPS, city maps, and pixel screens |
Solved Examples and Exercises in Coordinates
The chapter gives you in-text solved examples first, then exercises to try on your own. Practise the solved examples before you attempt each set.
- Exercise 1.1: naming positions in a room using coordinates.
- Exercise 1.2: plotting points and reading a graph.
- End-of-Chapter Exercises: distance, midpoints, collinearity, and grid design.
- In-text solved examples: step-by-step models spread through the chapter text.
What Changed in the 2026-27 Coordinates Chapter
This chapter comes from the new Ganita Manjari book, which replaces the old 15-chapter NCERT Maths book. The new book is activity-based, so Coordinates is taught through room grids, maps, and hands-on plotting rather than dry rules. In the older book, this topic appeared much later as Coordinate Geometry. Now it opens the course as Chapter 1, which makes the plane a base for later chapters.
How to Read the Coordinates Chapter
Read the Class 9 Maths Book PDF Chapter 1 Coordinates with a pencil and graph paper beside you. Skim once to see the flow, then read slowly and plot each point as it appears. Work through the solved examples, and only then try the exercises. This skim, then detail, then examples, then exercises order helps the ideas stick.
