2x – y + 3z – 1 = 0 and 2x – y + 3z + 3 = 0

NCERT Class XII Mathematics Chapter - - Solutions

Question 49 - 54: In the following cases, determine whether the given planes are parallel or perpendicular, and in case they are neither, find the angles between them.

Question : 53 of 78

Marks: +1, -0

Solution:

The given planes are 2x – y + 3z – 1 = 0 and 2x – y + 3z + 3 = 0

Since,

\frac{2}{2} = \frac{-1}{-1} = \frac{3}{3}

∴ The planes are parallel.
