AI Drawing Prompt Reference

Draw two similar right triangles that are horizontally aligned but separated from each other. The left triangle is smaller, and the right triangle is larger, with their bases on the same horizontal line. Each triangle has a horizontal base, a vertical leg, and a hypotenuse, with right angle marks at the right angle vertices. Mark corresponding acute angles in both triangles with angle symbols to show they are equal. Place an input box near the base of the left triangle for entering its base length, another input box near the vertical leg of the right triangle for entering that leg's length, and a third input box near the vertical leg of the left triangle for entering that leg's length. Connect corresponding vertices of the two triangles with line segments to illustrate the similarity. The overall layout should be clear for observing the proportional relationships.
