quadrant
Ninety-degree arc section
A quadrant is one of four parts created by dividing something along two perpendicular lines.
In coordinate geometry, the four quadrants are the sections of a plane divided by the x and y axes.
In navigation, a quadrant was an instrument for measuring angles, shaped as a quarter circle.
The word extends to any of four divisions: the northeast quadrant of the city, the upper right quadrant of the screen.
