Question

What are quadrants?

Answer 1

Explanation about Quadrants:

A Quadrant is a region enclosed by the intersection of $x-\mathrm{axis}\mathrm{and}y-\mathrm{axis}$. The two- dimensional cartesian plane is divided into four quadrants by $x-\mathrm{axis}\mathrm{and}y-\mathrm{axis}$. And the point of intersection of these two axes is the origin.

The $y-\mathrm{axis}$ is called the Vertical axis and the $x-\mathrm{axis}$ is called the Horizontal axis.

Sign of the coordinates in each quadrant are:

Quadrants	$x-\mathrm{coordinate}$	$y-\mathrm{coordinate}$
First (I)	Positive $(+)$	Positive$(+)$
Second (II)	Negative$(-)$	Positive$(+)$
Third (III)	Negative$(-)$	Negative$(-)$
Fourth (IV)	Positive$(+)$	Negative$(-)$

The sign of the coordinates in each quadrant are represented in the graph as:

Hence, a quadrant is region enclosed by the intersection of $x-\mathrm{axis}$ and $y-\mathrm{axis}$.
