Question

In the figure, the distance between the two lines AB and PQ is always constant. Then,
$\overleftrightarrow{AB}$ is ___ to $\overleftrightarrow{PQ}$

Answer 1

Given that the distance between the two lines AB and PQ is always constant.
Parallel lines are non - intersecting lines that never meet. Therefore,
$\overleftrightarrow{AB}||\overleftrightarrow{PQ}$
