AI Drawing Prompt Reference

Draw a square and rotate it around point E to create a new square. First, connect points A and D, B and A, C and B, D and C to form the square. Then, rotate points C and D around point E to generate C' and D', and connect C' and D' to form a new side. Next, rotate points A and B around point E to generate A' and B', and connect A' and B' to form another new side. Finally, rotate points B and C around point E to generate B' and C', and connect B' and C' to form the last new side.
