In the chapter Coordinate Geometry, students learn about how a point can be represented on a plane or space. 3D geometry is essential for locating a point in space. Coordinate Geometry helps in determining the point on planes. The advantage of learning this chapter is tremendous in future applications.

With the help of this chapter, students will learn how to locate a point with the help of the x and y-axis. You will draw the point on the plane depending on the question asked. The application will be helpful when it comes to identifying a location on the map.

The important topics that are covered in NCERT Class 9 Maths Chapter 3 are given in the table below:

Exercise No. | Important Topics |
---|---|

3.1 | Introduction to Coordinate Geometry |

3.2 | Cartesian System |

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

NCERT Class 9 Maths Chapter 3 Coordinate Geometry comprises important points that students must remember if they want to do well in their exams. Students can refer to these points below:

- Cartesian Plane:
- In order to locate the position of a point in a plane, we require two perpendicular lines. One of them is horizontal and another is vertical. The plane is called the Cartesian plane and the lines are known as the coordinate axes. The horizontal line is called the X− axis and the vertical line is known as the Y− axis.
- The coordinate axes divide the plane into four parts which are known as quadrants.
- The point of intersection of the coordinate axes is called the origin.
- The distance of a point from Y− axis is called its x− coordinate, or abscissa and the distance of the point from X− axis is called its y− coordinate or ordinate.

- Position of a Point:
- If x and y denote respectively the abscissa and ordinate of a point P, then (x, y) are called the coordinates of the point P.
- The y− coordinate of every point on the x− axis is zero. So, the coordinates of any point on the x− axis are of the form (x, 0).
- The x− coordinate of every point on the y− axis is zero. So, the coordinates of any point on the y− axis are of the form (0, y).
- The coordinates of the origin are (0, 0).
