Question

km and np are parallel lines. which angles are vertical angles? ∠poq and ∠nol ∠poq and ∠mlo ∠poq and ∠mlj ∠poq and ∠pol

Explanation:

Vertical angles are formed when two lines intersect. They are opposite each other and are equal in measure. In the given diagram, the lines $JQ$ and $NP$ intersect at point $O$. $\angle POQ$ and $\angle NOL$ are opposite each other at this intersection.

Answer:

$\angle POQ$ and $\angle NOL$
