老鹰在猎取地面小动物时,常常采取一个最优的角度,从空中俯冲下来直达猎物所处的位置,它懂得“两点之间线段最短”.在长方形土地的一角有一条狗,当你站在它的对角呼唤它时,它一定会沿着对角线穿过田野,向你奔来!它也知道“三角形的一边小于其它两边之和”.壁虎在捕捉昆虫时,总是沿着一条螺旋形曲线爬行,它也认识“螺旋线”!看来,“两点之间线段最短”这一公理,很多动物也掌握了,并且运用得非常熟练!下面看看它们眼中的最短路程. When hunting for ground animals, the eagle often takes an optimal angle, diving down from the air to reach the quarry where it knows “the shortest line between two points.” There is a dog in the corner of the rectangular land When you stand by its diagonals and call it, it must be diagonally across the field, running towards you! It also knows that “the side of the triangle is smaller than the sum of the other two.” When the gecko catches an insect, It always follows a spiral curve, and it also knows “Spiral ”! It seems that “the shortest line between two points ” is an axiom that many animals have mastered and are very skilled to use! Look at the shortest distance in their eyes.
