The two lines $x = a y + b, z = cy + d;$ and $x = a^{'} y + b^{'}, z = c^{'} y + d^{'}$ are perpendicular to each other if

Options:

Answer:

Solution:

Equation of lines $\frac{x - b}{a} = y = \frac{z - d}{c}$ $\frac{x - b ^{'}}{a ^{'}} = y = \frac{z - d ^{'}}{c ^{'}}$ Lines are perpendicular $\Rightarrow a a^{'} + 1 + c c^{'} = 0$
