Introduction to Three-Dimensional Geometry
त्रि-आयामी ज्यामिति का परिचय
In Class 11 Mathematics, the chapter Introduction to Three-Dimensional Geometry introduces the coordinate system used to represent points in space. Students learn about the three coordinate axes, coordinate planes, and the coordinates of a point in three dimensions. The chapter also develops the distance formula for finding the distance between two points in 3D space, forming a foundation for later study of spatial geometry and vectors.
