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?

Quadrilateral WXYZ is rotated 90º counterclockwise about the origin

Quadrilateral WXYZ is rotated 90º clockwise about the origin

Quadrilateral WXYZ is rotated 180º about the origin

Quadrilateral WXYZ is rotated 45º about the origin

Answer 1

As we can see on the picture point W, was rotated counterclockwise, and it is rotated 90⁰. If you draw all other points you will see that they are rotated same way.

Answer is A. Quadrilateral WXYZ is rotated 90º counterclockwise about the origin
