AI Drawing Prompt Reference
Draw a complex geometric figure based on Dürer's geometry, including a semicircle and two quadrilaterals with intersecting line segments. Start by creating points D and C on the x-axis and drawing a semicircle c with C and D as endpoints. Then create point B on the y-axis and draw quadrilateral vierhoek1 with vertices A, B, D, and C. Next, create point E on the x-axis and point H on a ray, and draw quadrilateral vierhoek2 with vertices E, F, G, and H. Construct a series of line segments and find intersection points I, J, K, L, M, N, O, P, Q, and R. Draw an ellipse k with vertices E, I, K, M, and O, and find foci T and U. Finally, find the midpoint V of E and H, and translate point D to V.
