Notes on  Coordinates System

coordinate system is a method for identifying the location of a point on the earth. Most coordinate systems use two numbers, a coordinate, to identify the location of a point. Each of these numbers indicates the distance between the point and some fixed reference point, called the origin

Cartesian Cartesian System

A Cartesian coordinate system or Coordinate system,is used to locate the position of any point and that point can be plotted as an ordered pair (x, y) known as Coordinates. The horizontal number line is called X- axis and vertical number line is called Y-axis and the point of intersection of these two axes is known as origin and it is denoted as ‘ O ‘.

Quadrants of Coordinate System

The Coordinate axes XX’ and YY’ divides the cartesian plane into 4 quadrants. In fig.  shown below:

RS Aggarwal Class-8 Coordinates System and Linear Graph ICSE Maths

  1. The region XOY is called first quadrant
  2. The region X’OY is called second quadrant
  3. The region X’OY’ is called third quadrant
  4. The region Y’OX is called fourth quadrant

Sign Convention

The ray OX on X-axis is taken as positive, OX’ as negative X-axis, OY on Y-axis as positive and OY’ as negative.

Accordingly, the distance measured along OX will be taken as positive and along OX’ will be negative. Similarly, the distance along OY will be taken as positive and along OY’ will be negative.

I- quadrant (+,+)

II-quadrant (-, +)

III-quadrant(-,-)

IV-quadrant(+,-)

Applications of Coordinates System

  • The coordinate plane concept is used in route maps.
  • It is also used to locate the position of aircrafts in sky
