NCERT Solutions for Class 11 Maths Chapter 12: Points to Remember

Students can note down some of the important points related to 3D Geometry as mentioned below:

  • In three dimensions, the coordinate axes of a rectangular Cartesian coordinate system are three mutually perpendicular lines. The axes are called the x, y and z axes.
  • The three planes determined by the pair of axes are the coordinate planes. These planes are called xy, yz and zx planes, and they divide the space into eight regions known as octants.
  • The coordinates of a point PP in the space are the perpendicular distances from P on three mutually perpendicular coordinates planes yz, zx, and xy, respectively. The coordinates of a point P are written in the form of triplets like (x,y,z).
  • The coordinates of a point are also the distances from the origin of the feet of the perpendiculars from the point on the respective coordinate axes
  • The coordinates of any point on:
    (a) x-axis are of the form (x,0,0)
    (b) y-axis are of the form (0,y,0)
    (c) z-axis are of the form (0,0,z)
    (d) xy-plane are of the form (x,y,0)
    (e) yz-plane are of the form (0,y,z)
    (f) zx-plane are of the form (x,0,z)
