Overview of Class 9 Maths Chapter 3 – Coordinate Geometry
Chapter 3 of Class 9 Maths, titled “Coordinate Geometry,” introduces the concept of coordinate systems used to describe the position of points on a plane. Here’s a summary of the key topics covered:
1. Introduction to Coordinate Geometry
Understanding the Cartesian coordinate system with x and y axes.
The coordinate plane (also known as the Cartesian plane) and its quadrants.
2. Plotting Points
How to plot points using coordinates (x, y).
Identifying the position of a point based on its coordinates.
3. Distance Formula
How to calculate the distance between two points using the distance formula:
Distance = √((x2 - x1)2 + (y2 - y1)2)
4. Section Formula
Finding the coordinates of a point that divides a line segment into a given ratio.
Using the formula:
Coordinates = ((m x2 + n x1) / (m+n), (m y2 + n y1) / (m+n))
5. Midpoint Formula
Determining the midpoint of a line segment with endpoints (x1, y1) and (x2, y2).
The formula:
Midpoint = ((x1 + x2) / 2, (y1 + y2) / 2)
6. Applications
Practical uses of coordinate geometry in solving problems related to distance, midpoint, and section of a line.
This chapter lays the foundation for understanding how geometric concepts are represented and analyzed using coordinates.
