Question

which angles are vertical angles?
∠por and ∠nom ∠qrt and ∠srt
∠nor and ∠qro ∠pom and ∠srt

Explanation:

Step1: Recall the definition of vertical angles

Vertical angles are the angles opposite each other when two lines cross.

Step2: Analyze each option

• For $\angle POR$ and $\angle NOM$: When lines $NP$ and $NT$ cross at point $O$, $\angle POR$ and $\angle NOM$ are opposite each other.
• For $\angle QRT$ and $\angle SRT$: These are adjacent angles (they share a common side $RT$ and a common vertex $R$), not vertical angles.
• For $\angle NOR$ and $\angle QRO$: These are not formed by the intersection of the same two lines in a vertical - angle - forming way.
• For $\angle POM$ and $\angle SRT$: These are not related as vertical angles.

Answer:

$\angle POR$ and $\angle NOM$
