Introduction to 3D Geometry Class 11 NCERT Solutions Chapter 12 is available below in pdf format, and a few solutions are also included in the exercises. These solutions explain the topics covered with examples so that students can easily relate to the notion being discussed.
Let P (x1, y1, z1) and Q (x2, y2, z2) be two points referring to a system of rectangular axes OX, OY and OZ. Distance between PQ is:
√ [(x2 - x1)2 + (y2 – y1)2 + (z2 – z1)2]
Let the two given points be P (x1, y1, z1) and Q (x2, y2, z2). The coordinates of the Point R(x, y, z) if:
x = (mx2 + nx1) / m + n, y = (my2 + ny1) / m + n, z = (mz2 + nz1) / m + n
x = (mx2 - nx1) / m - n, y = (my2 - ny1) / m - n, z = (mz2 - nz1) / m - n
x = (x1 + x2) / 2, y = (y1 + y2) / 2, z = (z1 + z2) / 2
( (x1 + x2 + x3) / 3, (y1 + y2 + y3) / 3, (z1 + z2 + z3) / 3 )
