This is a spinner divided into six equal sections, demonstrating basic geometric construction and rotation transformations. Using commands such as Circle, Point, Intersect, Sequence, Rotate, Vector, and CircleSector, a dynamic spinner can be created. Suitable for high-grade elementary or junior high school students to learn geometric transformations and probability statistics.
