**CBSE Class 9 Maths Chapter 3 – Coordinate Geometry NCERT Solutions**

NCERT Solutions for Class 9 Maths Chapter 3 deal with Coordinate Geometry. First of all, Coordinate Geometry is a branch of Geometry. Most noteworthy, it involves geometry using a coordinate system. Here the positions of points on the plane are described. Furthermore, it is described using an ordered pair of numbers. This chapter involves the concept of the Cartesian plane. Also, there is an association of name, terms, and notations with the coordinate plane. It also involves plotting a point in XY-plane.

**Sub-topics covered under NCERT Solutions for Class 9 Maths Chapter 3**

3.1 Introduction

3.2 Cartesian System

3.3 Plotting a Point in the Plane if its Coordinates are Given

**NCERT Solutions for Class 9 Maths Chapter 3**

First of all, Coordinate Geometry will build the foundation for college-level Mathematics. It is certainly the foundation of fields of geometry. Furthermore, the subject has a huge application in Physics. Therefore, this chapter will help students become scientists. Also, in engineering, there is a lot of use of Coordinate Geometry. Coordinate is also necessary for aviation, space science, and rocket sciences. Hence, it becomes clear that Coordinate will prepare students for a lot of fields. Ignoring this subject would probably be harmful to a student’s education.

#### Below is a brief explanation of the sub-units of chapter 3:

**3.1 Introduction –** This part gives a general idea of Coordinate Geometry. Above all, the plane has a coordinate system here. Furthermore, every point has a pair of real numbers coordinates.

**3.2 Cartesian System –** This is the most common coordinate system. Here each point has an x-coordinate. This x coordinate shows the point’s horizontal position. Furthermore, the coordinate represents the vertical position of the point. Also, they appear as a pair(x,y). Use of the Cartesian System can also be made for three-dimensional geometry.

**3.3 Plotting a Point in the Plane if its Coordinates are Given –** Here placing of points in the plane takes place. This happens when we know the coordinates already. This method is “plotting the point”.
