AI Drawing Prompt Reference

Draw a geometric construction showing how to create polygons and their incircles using rotation and vector operations. Start by constructing several polygons, find midpoints of their sides, connect these midpoints, and determine the intersection points of these segments. Use these intersection points to form new polygons and illustrate their inscribed circles.
