AI Drawing Prompt Reference

Draw a 30-60-90 triangle by first creating point B at the intersection of the coordinate axes, then constructing a triangle with points A, B, and C, and labeling its angles as α, β, and γ. Next, take the midpoint D on side BC, and create another triangle with points G, E, and F at the intersection of the axes, and label its angles as δ, ε, and ζ. Finally, take the midpoints H and I on sides EF and FG, respectively.
