AI Drawing Prompt Reference

Draw a geometric figure with multiple polygons and a symmetry line. Start by creating several points on the x-axis and use them to construct various polygons. Then, draw a symmetry line and reflect each polygon across this line to create new polygons. Finally, combine the reflected and original polygons to showcase the geometric transformation of line symmetry.
