Collinearity

बिंदुओं की समरेखीयता

In this Class 9 Mathematics topic from Coordinate Geometry, students learn the meaning of collinearity: when two or more points lie on the same straight line. They practise locating and plotting points on the Cartesian plane, observing their alignment, and using coordinate-based methods to decide whether a set of points is collinear. The topic strengthens understanding of ordered pairs, axes, straight lines, and geometric relationships, while developing accuracy in reading and interpreting coordinate diagrams.
