Answer:
Point C' coincides with point E.
point D' coincides with point F.
Step-by-step explanation:
Find the value of angle O in triangle ΔBOC where O is the center of the hexagon. Once you find it, devide it by the total value of counterclockwise rotation (240°) to find how many times the point labaled C moves to the left. The value of angle O in triangle ΔCOD is the same as the value of angle O in triangl we ΔBOC, so the amount that point D moves to the left is the same.
