The scene shows a colored 2D polygon, a rotation center marked by a small circular marker, and a dashed target outline indicating the final orientation. Only orientation changes. Rotate the polygon in the counterclockwise direction. First note the polygon’s initial orientation and the marked center, then read the dashed outline to know the target orientation. Rotate the polygon counterclockwise around the center until it completely overlaps the dashed outline with no offset. Keep size unchanged, keep a line to the center, and end with the polygon exactly matching the dashed outline. Only modify what the task requires; keep the background and any other element unchanged. Output 4 images at uniform rotation progress (1/4, 2/4, ..., 4/4).
