📘 Chapter Summary (Active Voice + SEO)
📍 Introduction to Coordinates
This chapter explains how we locate positions using a coordinate system. It connects maths with real-life navigation and everyday situations.
🧭 Cartesian Plane Basics
The chapter introduces the x-axis and y-axis, which meet at the origin (0,0). We represent every point as (x, y) to show horizontal and vertical distances.
🔢 Quadrants and Signs
The coordinate plane forms four quadrants. Each quadrant shows a different combination of positive and negative values, helping us identify direction.
🏠 Real-Life Applications
The chapter uses real-life examples, like mapping a room, to show how coordinates help us locate objects accurately.
📏 Distance Between Points
It teaches how to calculate distance between two points using the Pythagorean theorem, making measurement simple and clear.
