*In that applet we established that there is a sequence of paths that come closer and closer the to the hypotenuse of an isosceles right triangle. Each of the paths in the sequence has the same length; i.e., the sum of the lengths of the two perpendicular legs of the triangle. In an isosceles right triangle with hypotenuse of length*
