AI Drawing Prompt Reference

Draw a geometric construction: start with a line through two points, then a parallel line through a third point, and another parallel line through a fourth point. From the fourth point, draw a perpendicular to the last line. Place a point on each of the three lines. Connect points to form three angles: one at the fourth point between the perpendicular point and the perpendicular foot, another at the intersection of the perpendicular with the second line between a point on that line and the intersection with the first line, and a third at the intersection of the perpendicular with the first line between a point on the second line and the perpendicular foot. Mark all intersection points.
