AI Drawing Prompt Reference

Draw a horseshoe arch formed by two intersecting circles and auxiliary lines. Start with a horizontal segment as the base, find its midpoint, and draw a large circle centered there. Construct a rotated point above the base to define the arch's starting arc. Then draw a smaller circle with another center, intersecting the large circle, and use reflection and rotation to create the symmetric arch outline. Connect key points to form triangles and segments, mark an angle, and add multiple arcs and auxiliary lines to complete the geometric and trigonometric construction.
