Answer
$VUTSR ≅ ONMLK$
Work Step by Step
In congruent polygons, vertices are named in the exact order of their matching angles and sides.
If $RSTUV$ is congruent to $\triangle KLMNO$, then vertex $R$ corresponds to vertex $K$, vertex $S$ corresponds to vertex $L$, vertex $T$ corresponds to vertex $M$, vertex $U$ corresponds to vertex $N$, and vertex $V$ corresponds to vertex $O$.
Therefore, $VUTSR ≅ ONMLK$.
