General's Horse Drinking Problem — Geometric Construction for Shortest Path

2020-04-01 13:46
This GeoGebra applet demonstrates the classic 'General's Horse Drinking' optimization problem: given two points A and B on the same side of a line (river), find the shortest path from A to a point P on the line and then to B. By constructing the reflection of a point across the line and applying the principle that the shortest distance between two points is a straight line, the optimal drinking po
