Summary
| Description |
English: Composed with itself repeatedly, similarity F of center S enlarges the smallest regular pentagon into successive concentric pentagons, in manner that the outline of each one passes through all vertices of the previous pentagon, of which it is the image under F. If transformation F is iterated indefinitely, then A and K are the starting points of two infinite spirals. Similarity F is direct, its oriented angle equals + 18°, its ratio two times as written at the image bottom.
