AI Drawing Prompt Reference

Draw a quadrilateral and connect the midpoints of its four sides to form a new quadrilateral. First, draw the four sides of the original quadrilateral, then find the midpoint of each side and connect these midpoints to form a new quadrilateral. Finally, display both the original quadrilateral and the new quadrilateral formed by connecting the midpoints.
The prompt above was compiled from the original drawing commands and is for reference only.
