The ratio is implicit in, as of the base AB: (1+√5) to the height BD: 2, same as that of 2 to ED: (√5-1). Of course, the diagonal BF of the first rectangle cuts the square's side, ie. the base of the second rectangle, at the same distance from E as the side ED, defining the next square as c-D-E, and the same phi ratio for the rectangle in E-D-B. This recurrent criterion may define any new inner rectangle, as well as the outer ones, since the Phi perfection is virtually resolved in its infinity. |
