Question

km and np are parallel lines. which angles are vertical angles? ∠mlo and ∠mlj ∠mlo and ∠klo ∠mlo and ∠nol ∠mlo and ∠klj

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 of lines in the figure

The lines $QJ$ and $KM$ intersect at point $L$, and the lines $QJ$ and $NP$ intersect at point $O$.

Step3: Identify vertical - angle pairs

$\angle MLO$ and $\angle NLQ$ are vertical angles, and $\angle MLO$ and $\angle NOL$ are vertical angles since they are formed by the intersection of the transversal $QJ$ with the parallel lines $KM$ and $NP$.

Answer:

$\angle MLO$ and $\angle NOL$
