### NCERT Solutions For Class 11 Maths Chapter 12 – Introduction To Three Dimensional Geometry – Chapter Summary

Geometry is a well-known branch of mathematics and is one of the ancient ones too. In the lower classes, we have studied geometry which is related to a single plane. For instance, we used to locate a point in a plane using the *Coordinates* with reference to the coordinate axes which comes under 2D Geometry. But, in real life, we do not deal with points lying in a plane only. For example, if we have to locate the position of a ball thrown in the air at a particular instant or the position of an aeroplane as it flies from one place to another at different times during its flight.

Thus to mathematically solve such problems, the study of three-dimensional geometry comes into the picture. Thus to start with we will discuss on the coordinate axes of a rectangular Cartesian coordinate system which are three mutually perpendicular lines. The axes here will be called as x, y and z-axes. Whereas the planes which we study will be XY, YZ and ZX-planes. Also, the three coordinate planes divide the space into eight parts known as octants.

We have now provided you with all the details on NCERT Solutions For Class 11 Maths Chapter 12. So let’s get started with solving exercise questions and make the best use of the solutions provided here for reference.
