Question

which angles are alternate interior angles? ∠stw and ∠vwt ∠stw and ∠vwy ∠stw and ∠xwt ∠stw and ∠utr

Explanation:

Step1: Recall alternate - interior angles definition

Alternate - interior angles are two non - adjacent interior angles on opposite sides of a transversal.

Step2: Analyze each option

For the given lines and transversal, $\angle STW$ and $\angle VWT$ are non - adjacent interior angles on opposite sides of the transversal $YR$. The other pairs do not meet the criteria for alternate - interior angles.

Answer:

$\angle STW$ and $\angle VWT$
