Distance between two skew lines I have 2 skew lines $L_A$ and $L_B$ and 2 parallel planes $H_A$ and $H_B$.
The line $L_A$ lies in $H_A$ and $L_B$ in $H_B$. If the equations of $H_A$ and $H_B$ are given like this:
$x+y+z = 0$ (for $H_A$)
$x+y+z = 5$ (for $H_B$) 
Can I just simply say that the distance between two lines $L_A$ and $L_B$ is 5 since there the two planes they lies are separated apart by 5?

Yes,the shortest distance between the skew lines will equal the distance between the planes.
