令有动点的距离之和最短问题在各类初中数学竞赛中经常出现,解决这类问题时,将轴对称的性质和两点之间线段最短这两个知识点巧妙结合,这类问题就能迎刃而解.
The problem of the shortest distance between moving points is often seen in all kinds of junior high school math competitions. To solve this type of problem, the axisymmetric property and the shortest line segment between the two points are combined ingeniously. Can be solved.
