Quadrant

Definition

A quadrant is one of the four sections of the coordinate plane that are divided by the x-axis and y-axis. Each section is defined by its position relative to these axes.

5 Must Know Facts For Your Next Test

1. The coordinate plane is divided into four quadrants, numbered I through IV in a counterclockwise direction starting from the upper right.
2. Quadrant I contains points where both x and y coordinates are positive.
3. Quadrant II contains points where x coordinates are negative and y coordinates are positive.
4. Quadrant III contains points where both x and y coordinates are negative.
5. Quadrant IV contains points where x coordinates are positive and y coordinates are negative.
