Chapter 22
Introduction to Three-Dimensional Geometry
A fly sits in the corner of a room. How do you tell a friend exactly where it is? You need three numbers: how far along one wall, how far along the other, and how high above the floor. This chapter gives every point in space its three coordinates. Then it measures with them: the distance between two points, the point that divides a segment in a given ratio, the centre of a triangle or a tetrahedron, the sphere, and the cuboid. It covers the Class 11 unit of the Indian syllabus (NCERT, JEE Main) and the matching ideas of A-Level, IB and AP. Lines and planes come in the later chapter on three-dimensional geometry. Python checks every answer on the computer.
