[kwษdrษnt ]
Definition
mathematics area
A quadrant is a quarter of a circle or the plane area enclosed by two radii and the arc between them. In the Cartesian coordinate system, a quadrant refers to one of the four sections of the plane divided by the x and y axes. Each quadrant is defined by the signs of the coordinates in that section, specifically positive or negative. Quadrants are crucial for graphing and understanding the position of points on the Cartesian plane.
Synonyms
Examples of usage
- The point is located in the third quadrant.
- An angle of 90 degrees opens into the first quadrant.
- We plotted the function in all four quadrants.
- Each quadrant represents a different sign combination of coordinates.

Origin of 'quadrant'
The word 'quadrant' comes from the Latin word 'quadrans', which means 'a fourth part' or 'quarter'. This term is derived from 'quadra', meaning 'square', which is related to the word 'four'. The use of 'quadrant' can be traced back to ancient geometry, where it was used to describe a quarter of a circle, particularly in the context of circular diagrams and astrolabes. In mathematics, the concept of dividing a space or angle into four parts has real significance, extending to various disciplines, including astronomy and navigation. The term has evolved over centuries, retaining its relevance in modern mathematical vocabulary and practical applications.
