AI Drawing Prompt Reference
Draw a square, then rotate it 90 degrees four times to generate a new square each time, resulting in four equal parts. First, draw a square, then take two points on the x-axis as new vertices, draw a new square, and rotate one of its vertices 90 degrees four times, generating a new vertex each time, and finally use these vertices to draw four equal parts.
