Question

Quadrilateral WXYZ is located at W(3, 6), X(5, -10), Y(-2, -4), Z(-4, 8). A rotation of the quadrilateral is located at W�(-6, 3), X�(10, 5), Y�(4, -2), Z�(-8, -4). How is the quadrilateral transformed?
A. Quadrilateral WXYZ is rotated 90º counterclockwise about the origin
B. Quadrilateral WXYZ is rotated 90º clockwise about the origin
C. Quadrilateral WXYZ is rotated 180º about the origin
D. Quadrilateral WXYZ is rotated 45º about the origin

Answer 1

Did you notice that W changed from (3,6) to W'(-6,3)?
Close you eyes, concentrate and see the point move from x=+3 to y=+3.
What rotation would that be?
Check with another point just to be sure.
