Cartesian system, quadrants, and axes

कार्तीय निर्देशांक तंत्र, चतुर्थांश और अक्ष

In Class 9 Mathematics, this topic from Coordinate Geometry introduces the Cartesian plane as a way to locate and describe points precisely. Students learn about the x-axis, y-axis, origin, coordinate pairs, and the four quadrants. They understand how the signs of the coordinates change from one quadrant to another, plot ordered pairs on a graph, and read the coordinates of given points. These ideas build a clear foundation for representing geometric relationships using numbers and diagrams.
