Answer:
Step-by-step explanation:
Given the coordinates of the vertices of the quadrilateral as;
Note that whenever a point P(x, y) is rotated 180 degrees counterclockwise about the origin, the image will be P'(-x, -y)
So if quadrilateral ABCD is rotated 180 degrees counterclockwise about the origin, then the coordinates of the vertices of quadrilateral A'B'C'D' will be;
