10-13.

Crystal is amazed! She graphed $ΔABC$ using the points $A(5, –1)$, $B(3, –7)$, and $C(6, –2)$. Then she rotated $ΔABC$ $90º$ counterclockwise ($↺$) about the origin to find $ΔA′B′C′$. Meanwhile, her teammate took a different triangle ($ΔTUV$) and rotated it $90º$ clockwise ($↻$) about the origin to find $ΔT′U′V′$. Amazingly, $ΔA′B′C′$ and $ΔT′U′V′$ ended up having exactly the same points! Name the coordinates of the vertices of $ΔTUV$.
