Over a quiet lake, Half a foot above water grew a Lily. It grew alone. And the wind blew it over to the side. There is no more flower over the water. A fisherman in early spring found the Lily two feet away from where it used to grow. And the question is: How deep is the water in the lake Where the Lily grew.

    It was x feet below, That the lily grows. To this distance from the root We add half a foot, The hypotenuse H will become. Add the square Of the distance from where The lily used to grow, And the square of x feet below, We get H^2, by Pythagoras' rule of thumb.
