3d Geometry Class 12 introduces the concept of three-dimensional geometry while giving an overview and revision of analytical geometry in two dimensions. This chapter explains three-dimensional geometry using Cartesian methods. The other topics included in this chapter are the basic concepts of vectors and ways to use vector algebra in solving problems related to three-dimensional geometry. Apart from this, students learn and can practise the concepts of directions and e-direction cosines along with the direction ratios of a line joining two points.
Finally, Three Dimensional Geometry class 12 helps students in learning the equations of lines and planes in space under the following conditions and much more:
