动物中,壁虎有一种颇有情趣的求生本领:它在遇到天敌时,能将自己的尾巴断开,欢蹦乱跳的尾巴吸引了敌人的注意,壁虎得以逃生,有趣的是有些几何问题,把图形去掉一半,用剩下的一半图形,仍然能对这个几何问题进行求解或证明,我们称这种方法为“再生法”. Animals, Gecko has a rather interesting survival skills: it encounters natural enemies, they can disconnect their tails, romp tail attracted the attention of the enemy, the gecko was able to escape, the funny thing is that there are some geometric problems, the graphics If you remove half, you can still solve or prove this geometric problem with the remaining half of the graph. We call this method “regeneration method.”
