3D Geometry

This chapter deals with coordinates of a point in space. It also explains the position vector of a point in apace with the help of solved examples.

In this chapter, we will learn the equation of a line passing through a given point and parallel to a given vector. It explains the collinearity of three given points and the shortest distance between two lines.

This chapter deals with the general equations of a plane in a Cartesian and intercept form. It deals with equations in various forms and passing through different points. We will also learn the condition for the coplanarity of two lines.
