AI Drawing Prompt Reference

Draw an angle in standard position, showing the unit circle and angle sketching. Start with a ray as the initial side, then draw rays at different angles (e.g., 30°, 45°, 60°, 90°) around the origin, creating mirrored versions. Finally, randomly select an angle, label its measure, and display the angle between two rays.
