In Chapter 1 – Orienting Yourself: The Use of Coordinates, you will learn how coordinates can be used to describe and locate points in two-dimensional space. The chapter develops coordinate geometry through practical situations, graphs, reasoning and problem-solving.

• 📍 Understand the 2-D Cartesian Coordinate System – Learn about the x-axis, y-axis, origin and coordinates.
• 📊 Locate and Plot Points – Represent points using ordered pairs and identify their positions on the coordinate plane.
• ➕➖ Work with Positive and Negative Coordinates – Understand coordinates in all four quadrants and the signs associated with each quadrant.
• 📏 Find Distances Between Points – Calculate horizontal, vertical and general distances between points using coordinate methods and the Baudhāyana–Pythagoras Theorem.
• 🎯 Find Midpoints – Explore how the coordinates of a midpoint are related to the coordinates of the endpoints of a line segment.
• 🔄 Explore Reflection of Points and Figures – Investigate how coordinates change when figures are reflected across an axis while lengths are preserved.
• 🧠 Apply Coordinate Geometry to Real-Life Situations – Use coordinate ideas to represent locations, layouts, roads and other spatial situations.
• 🧩 Develop Mathematical Reasoning and Problem-Solving Skills – Use coordinates, distances and geometric relationships to solve increasingly challenging problems.
