Quadrants: 2

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. The axes of a two-dimensional Cartesian system divide the plane into four infinite regions, called quadrants, each bounded by two half-axes. The axes themselves are, in general, not part of the respective quadrants. Learn what a quadrant is in Maths, how to identify all four quadrants on the coordinate plane, and tips for remembering signs and solving questions easily. Learn all four quadrants of a coordinate system. The plane of the graph paper is divided into four regions by the coordinate axes and the four regions are called quadrants.
