NCERT Solutions for Class 11 Chapter 12 Introduction To Three Dimensional Geometry


In three dimensions, the coordinate axes of a rectangular cartesian coordinate system are three mutually perpendicular lines. These axes are called the X, Y and Z axes. Student will learn the basic concepts of geometry in three-dimensional space. The three planes determined by the pair of axes are the coordinate planes. The chapter discusses the concept of coordinate axes and coordinate planes in three dimensions, coordinates of a point, distance between two points and section formula, in detail.
