Answer:
B. ∠VRT and ∠WRS
Explanation:
We know that,
'Vertical angles are the pairs of opposite angles made by two intersecting lines.'.
Since, in the figure, we have,
The intersecting lines are VS and WT and they intersect at the point R.
So, we get,
∠VRT, ∠WRS and ∠VRW, ∠TRS are the vertical angles.
Thus, according to the options,
B. ∠VRT and ∠WRS are the vertical angles.
