2. Set the polygon parameter to a five-pointed star and draw a five-pointed star on the stage.

3. Select any deformation tool to move the center point of the five-pointed star outward, open the deformation window, adjust the angle to 30, and then click on the lower right corner to copy and apply deformation.

4. With the center point as the axis, a duplicated deformed five-pointed star will appear at 30 degrees in the upper right corner.

5, in the same way, do it a few times, and finally the circle of the five-pointed star will come out.
