Class 12 Maths NCERT Three Dimensional Geometry
The chapter Three Dimensional Geometry in Class 12 NCERT Mathematics introduces students to the concepts of points, lines, and planes in three-dimensional space. It covers coordinates of points in 3D, distance between two points, direction ratios, and direction cosines. Students also learn equations of lines and planes, angle between lines, planes, and line-plane intersections, as well as the shortest distance between skew lines.
NCERT provides clear explanations, solved examples, and exercises to develop strong problem-solving and analytical skills. This chapter is essential for CBSE Class 12 board exams and competitive exams like JEE Main, JEE Advanced, and engineering entrance tests, where 3D geometry problems are frequently asked. Mastering Three Dimensional Geometry enables students to visualize spatial problems, apply vector and coordinate methods effectively, and build a solid foundation for higher studies in mathematics, physics, and engineering.
