AI Drawing Prompt Reference

Draw an optimization problem example showing how to minimize road lengths between towns using mathematical methods. Start by plotting a point and a line segment, then mirror the point across the segment to get a new point. Connect the original point to the new point. Next, connect the new point to two other points and find the intersection of the two resulting line segments. Based on the intersection, connect relevant points to form two polygons, and calculate the distances and angles involved, ultimately presenting a geometric figure with multiple elements and mathematical concepts.
