Introduction to Three Dimensional Geometry – NCERT Class 11 Mathematics Chapter 11 – Coordinate System, Points, Distances, and Basic Concepts
Introduces the three-dimensional coordinate system with mutually perpendicular axes and planes, defines coordinates of points in space, explains octants, derives the distance formula between points in 3D, discusses collinearity, planes and lines, and provides practical examples and exercises including centroid calculation. Also includes historical notes on the development of 3D geometry.
