Question

select all the pairs of vertical angles. ∠tsq and ∠tsv ∠tsq and ∠uvs ∠rsv and ∠uvx ∠rsv and ∠tsq

Explanation:

Vertical angles are formed when two lines intersect. They are opposite each other and are equal in measure.

• $\angle T S Q$ and $\angle U V S$: These are not vertical angles as they do not meet the definition of vertical angles (formed by the intersection of two lines and being opposite).
• $\angle R S V$ and $\angle T S Q$: These are vertical angles as they are formed by the intersection of lines $RT$ and $XQ$ and are opposite each other.

Answer:

$\angle R S V$ and $\angle T S Q$
