CBSE Class 9th Coordinate Geometry- Cartesian System

Nov 29, 2017 11:38 IST

    In this video we will learn about the Cartesian System of Geometry in which the coordinate plane is divided by the x and y axis.

    A Cartesian system is the one which specifies a point plotted uniquely on a plane by a pair of numerical coordinates, having a pre-defined distance from the two fixed perpendicular coordinates, measured in the same unit of length.

    • The numbers are represented on a number line on which the points are marked at equal distances.
    • Two number lines are taken and intersected perpendicularly at the point zero also called the origin.
    • The numbers on the right side of the horizontal number line, also x- axis, are positive and that on the left side are negative.
    • The numbers to the top of the origin of the vertical number line, also y-axis, are positive and that below the origin are negative.
    • The x- axis and the y-axis divide the coordinate plane into four parts called the quadrant.
    • The quadrants are named in an anti-clockwise order, starting with I, II, III and IV.
    • In the first quadrant both the x and y coordinates are positive
    • In the second quadrant x coordinate is negative and the y coordinate is positive
    • In the third quadrant both x and y coordinates are negative, and
    • In fourth quadrant x coordinate is positive and the y coordinate is negative.
    • Any point can be depicted on the coordinate plane by specifying its perpendicular distances from the x and y coordinates.
