AI Drawing Prompt Reference

Draw two regular hexagons and find their overlapping area. First, draw two regular hexagons and identify their intersection points. Center a circle at one of the intersection points and find a point on the circle. Use this point and the intersection point to draw a new regular hexagon. Then, draw multiple polygons using the sides of the hexagons and intersection points to form the boundaries of the overlapping region. Finally, measure and label the area of the overlapping region.
