AI Drawing Prompt Reference

Draw a geometric proof diagram with a common vertex C. Construct two triangles sharing C, one equilateral and the other formed by rotation. Draw several vectors from the origin to create right-triangle structures. Center multiple concentric circles at C, with radii corresponding to distances from C to various points. Mark key points and display an angle label to illustrate the relationship between trigonometry and circle geometry. Keep the layout clear for educational demonstration.
