 # NCERT Exemplar Class 12 Maths Solutions for Chapter 11 - Three Dimensional Geometry

NCERT Exemplar Class 12 Maths Chapter 11 Three Dimensional Geometry, are provided here for students to practice and prepare for the exam. While students have already studied vector algebra in the previous chapter, they will apply this concept to three-dimensional geometry to further make the study simple. In chapter 11, students will mainly learn about three-dimensional lines and planes, the angle between two lines and also find equations in vector forms. Some of the other specific topics include direction cosines and direction ratios, the equation of a plane, etc.
