Answer:
A rotation of 180 degrees counterclockwise about the origin is equivalent to the coordinate transformation ( , ) → ( − , − ) . A rotation of 270 degrees counterclockwise about the origin is equivalent to the coordinate transformation ( , ) → ( , − ) .
Step-by-step explanation:
After a 180° counterclockwise rotation around the origin, the coordinates of the vertices are transformed by changing the signs of their original x and y coordinates. The new coordinates of the vertices are D'(0, 3), E'(0, 8), B'(5, 8), and C'(5, 3).
