Question

When two lines are parallel, the distance between them is

• A. always equal
• B. not equal
• C. increases
• D. is constant

Answer 1

The correct option is D is constant

$\Rightarrow$ When two lines are parallel, the distance between them is $constant.$

$\Rightarrow$ Parallel lines remain the same distance apart over their entire length. No matter how far you extend them, they will never meet.

$\Rightarrow$ In order for two lines to be parallel, they must be drawn in the same plane.
