AI Drawing Prompt Reference

Draw a dynamic geometric figure composed of four connected polygons to demonstrate the effect of scaling lengths through rational multiplication. Start with a base segment and extend outward sequentially to form four connected polygons, each with sides increasing proportionally in length. From one endpoint of the base segment, draw four rays that intersect the outermost polygon, and connect each intersection point back to the starting point to form a dynamic segment, illustrating proportional relationships.
