Question

pr and su are parallel lines. which angles are supplementary angles? ∠stv and ∠pqt ∠stv and ∠utq ∠stv and ∠stq ∠stv and ∠rqo

Explanation:

Step1: Recall supplementary - angle definition

Two angles are supplementary if their sum is 180 degrees. Adjacent angles that form a straight - line are supplementary.

Step2: Analyze the angles around point T

$\angle STV$ and $\angle STQ$ form a straight - line at point T. So, $\angle STV+\angle STQ = 180^{\circ}$.

Answer:

$\angle STV$ and $\angle STQ$
