 Quadrant (plane geometry)

The two coordinate axes divide a Cartesian coordinate system in the plane into four open quadrants, distinguished by the signs of their coordinates. The positive quadrant is the first quadrant.

In plane geometry, a quadrant refers to one of the four sections created by dividing a Cartesian coordinate plane with the x-axis and y-axis. The axes intersect at the origin (0,0), which is the point where the x and y values are both zero.
