Question

jl and mo are parallel lines. which angles are vertical angles? ∠mnk and ∠onp ∠mnk and ∠mnp ∠mnk and ∠jkn ∠mnk and ∠jki

Explanation:

Step1: Recall vertical - angle definition

Vertical angles are formed when two lines intersect. They are opposite each other and are congruent.

Step2: Analyze the intersection

The lines $PI$ and $MO$ intersect at point $N$, and the lines $PI$ and $JL$ intersect at point $K$.

Step3: Identify vertical - angle pairs

Among the given options, $\angle MNK$ and $\angle ONP$ are vertical angles because they are formed by the intersection of lines $PI$ and $MO$ and are opposite each other.

Answer:

$\angle MNK$ and $\angle ONP$
