[0002] The general drinks horse model is derived from an actual problem in ancient times, and has become a classic model in junior high school mathematics geometry teaching after being refined and abstracted by mathematicians. The model describes that on the same side of a straight line (usually representing a river), there are two points (representing a general and a military camp respectively), and a point (representing a drinking water point) on the straight line is required to be found, so that the sum of the walking distances from the military camp to the point and from the point to the general is the shortest. This problem ingeniously combines symmetry, distance between a straight line and a point, and other geometric concepts, and is a specific embodiment of optimization thinking in the field of geometry.

[0003] In junior high school mathematics geometry teaching, the importance of the general drinks horse model is self-evident.

In addition, through the study of the general drinks horse model, students can also initially understand and grasp the optimization thinking, laying a solid foundation for their subsequent learning of more complex mathematical knowledge and solving practical problems. Therefore, the general drinks horse model is not only an important content in junior high school mathematics geometry teaching, but also an effective way to cultivate students' mathematical literacy and thinking ability.
