Learn about quadrants, the four regions of a two-dimensional cartesian system, with positive and negative values of x and y axes. Find out the sign convention, trigonometric values, plotting points, and uses of quadrants with examples and video. We will learn more about the four quadrants of a coordinate system in this article, as well as how to plot and locate points in each quadrant. 2.0 Cartesian Plane Quadrants and Coordinates In 2D geometry, the origin or the point of intersection separates the Cartesian plane into four regions called the Cartesian plane quadrants, referred to as Quadrants I, II, III, and IV. On the cartesian plane when the two axes, X-axis and Y-axis, intersect with each other at 90 º and there are four regions formed around it, and those regions are called quadrants. So, every plane has four quadrants each bounded by half of the axes.
