Question

which angles are vertical angles? ∠nol and ∠poq ∠nol and ∠noq ∠nol and ∠mlj ∠nol and ∠pol

Explanation:

Step1: Recall vertical - angle definition

Vertical angles are formed when two lines intersect. They are non - adjacent angles with a common vertex and their sides are formed by two pairs of opposite rays.

Step2: Analyze the given angles

In the figure, lines $KP$ and $JQ$ intersect at point $O$. $\angle NOL$ and $\angle POQ$ are non - adjacent angles, have a common vertex $O$, and their sides are formed by opposite rays.

Answer:

$\angle NOL$ and $\angle POQ$
