Mathematics can be both fantastic and challenging at the same time. Specially in class 10 when students have to give board paper. So our NCERT class 10 Mathematics Chapter 7 Coordinate Geometry notes will provide conceptual clarity to the students. It will work like a bridge for students between class room theory lecture and solving exercise at home.
These Class 10 Chapter 7 Coordinate Geometry Notes is a masterstroke for students who want to pursue a career in science, like becoming an engineer, scientist etc. Most of the concept given in class 11 maths have already been introduced in class 10 maths. So these notes are also the foundation of class 11 math.

Chapter 6: Triangles Notes
Chapter 8: Introduction to Trigonometry Notes
Below we have also given most important topics of NCERT Class 10 Mathematics chapter 7 Coordinate Geometry Notes. Students should revise these notes regularly to remember the chapter properly.
Important Topics of Coordinate Geometry
1. Coordinate axes:
Two perpendicular number lines intersecting at point zero are called coordinate axes. The point of intersection is called origin and denoted by ‘O’. The horizontal number line is the x-axis (denoted by X’OX) and the vertical one is the y-axis (denoted by Y’OY).
2. Cartesian plane is a plane formed by the coordinate axes perpendicular to each other in the plane. It is also called as xy plane.
The axes divide the Cartesian plane into four parts called the quadrants (one fourth part), numbered I, II, III and IV anticlockwise from OX.
Points on a Cartesian Plane
A pair of numbers locate points on a plane called the coordinates. The distance of a point from the y-axis is known as abscissa or x-coordinate. The distance of a point from the x-axis is called ordinates or y-coordinate.
3. Coordinates of a point:
- The x-coordinate of a point is its perpendicular distance from y-axis, called abscissa.
- The y-coordinate of a point is its perpendicular distance from x-axis, called ordinate
- If the abscissa of a point is x and the ordinate of the point is y, then (x, y) is called the coordinates of the point.
- The point where the x-axis and the y-axis intersect is represented by the coordinate point (0, 0) and is called the origin.
