AI Drawing Prompt Reference

Draw a triangle ABC, then rotate it 300 degrees around point B to create a new triangle A'B'C'. Connect A'B', B'D', D'E', E'F', F'G', and G'A' to form a hexagon. Next, find the perpendicular bisector of line segment c, intersect it with c to get point H, then connect H to point J, J to K, and K to C to form a closed shape.
