RD Sharma Solutions Class 12 The Plane

RD Sharma Solutions Class 12 Chapter 29

A plane is a flat, 2-dimensional surface having infinite dimension, but having zero thickness. Such that if any two points are taken on it, the line segment joining them lies completely on the surface. A plane in 3-dimensional space has the following equation

ax + by + cz + d = 0,

Where at least one of the values of a,b,c, must be a non-zero.

The three possible planes in 3-d coordinate system are

  1. xy plane, where the value of z coordinates is zero.
  2. y-z plane, where the value of x coordinate is zero.
  3. x-z plane, where the value of y coordinate is zero.
