AI Drawing Prompt Reference

Draw a polygon with a circle inside and several triangles. Obtain intersection points by crossing the circle with line segments, generate random angles to create sectors, and use angle bisectors and rotations to construct new shapes, finally adding vectors to indicate direction, demonstrating the geometric process of angle estimation.
