Three-Dimensional Geometry
Two aeroplanes fly in the same sky. Will they meet, or only seem to cross? A drone lands on a sloping roof. How far was it from the roof a moment ago? These questions live in three dimensions, and the answers come from lines and planes written as equations. In this chapter you describe a line by its direction and one point, find the angle between lines, measure the shortest distance between lines that never meet, and then do the same for planes. It covers the unit of the Indian syllabus (NCERT, JEE Main) and the matching topics of A-Level Further Maths and IB. Python checks every answer on the computer.
