Answer: R'=(6, -2)
S=(-6,9) ==> S'=(6, -9)
T=(-5,9) ==> T'=(5, -9)
U=(-5,2) ==> U'=(5, -2)
Explanation:
When rotated around the origin by 180 degrees, the rectangle will have all its coordinates' x and y values negated.
R=(-6, 2) ==> R'=(6, -2)
S=(-6,9) ==> S'=(6, -9)
T=(-5,9) ==> T'=(5, -9)
U=(-5,2) ==> U'=(5, -2)
