step one:
X(-3, 3) , Y(-7,5), Z(-3, 7)
change sign of vector but since it zero no need.
now add it with vector (0,0)
X(-3, 3) > X(-3, 3)
Y(-7,5) > Y(-7,5)
Z(-3, 7) > Z(-3, 7)
now apply rules.
270 about the origin is (x,y)→(y,−x)
X(-3, 3) → x(3,-3)
Y(-7,5)→ Y(5,-7)
z(-3,7)→ Z(7,-3)
Now, add 0 with it
same coordinates. :D
So it is the same! as the one u plotted
