Final answer:
To find the coordinates of point D' after a 90° clockwise rotation of quadrilateral CDEF, apply the rotation rules to the coordinates of point D. If D is at (x, y), then D' will be at (y, -x).
Step-by-step explanation:
If quadrilateral CD'EF represents quadrilateral CDEF rotated 90° clockwise about the origin, the ordered pair of D' would be determined by applying the 90-degree rotation transformation rules to the coordinates of point D.
When rotating a point 90 degrees clockwise about the origin, the coordinates (x, y) transform into (y, -x).
Therefore, if the coordinates of point D are (x, y), then after the rotation, the coordinates of D' will be (y, -x).
To find the specific coordinates, you would need the original coordinates of point D. As this information is not provided, a generic answer is given. In a real scenario, if D had coordinates (3, 4), for example, then after a 90° clockwise rotation, D' would be located at (4, -3).
