AI Drawing Prompt Reference
Draw a triangle with one side intersected by two parallel lines, creating two sets of intersection points. Start with two sides of the triangle, then add two auxiliary lines parallel to the base, each crossing both sides to produce four intersection points. Next, select one intersection point on each auxiliary line near the top vertex, and connect these two points to a vertex of the triangle with line segments. The figure illustrates how the side lengths change as the parallel lines move, demonstrating the concept of limits geometrically.
