Topics Covered in Exercise 3.1 class 9 Mathematics Questions

NCERT solutions for class 9 maths chapter 3 ex 3.1 covers the topic coordinate geometry and its concepts of representing the points on axes x-y. In this exercise, we aim to introduce some basic concepts of coordinate geometry.

Important Points

  1. To locate the position of an object or a point in a plane, we require two perpendicular lines. One of them is horizontal, and the other is vertical.

  2. The plane is called the Cartesian, or coordinate plane and the lines are called the coordinate axes.

  3. The horizontal line is called the x -axis, and the vertical line is called the y - axis.

Frequently Asked Questions

Question 1. What is coordinate geometry in ex 3.1 class 9 maths?

Answer 1. Coordinate geometry is the branch of geometry in which the positions of points on a plane is determined by an ordered pair of numbers, also referred to as coordinates.

Question 2. Who is the father of coordinate geometry?

Answer 2. Rene Descartes is widely regarded as the founder of coordinate geometry. His contributions to this field earned him the title of the "Father of Analytic Geometry". Because his name is derived from the Latin word Renatius cartesius, we know that the terms Cartesian plane and Cartesian coordinate system are derivatives of his name.
