When one half of the Square's diagonal is counted as 1, when extended
to the Phi-point, this distance becomes 1.6180339887.. i.e., Phi. .
A circle of the radius 0.6180339887.. will map exactly ten times
onto the Square's circumcircle, as this is the method of constructing
both the five and ten-pointed stars.
The Phi-point also performs Golden Section on the length kx -
of the Square's diagonal.
Similarly, a star drawn from the symmetrical point K2 to the far corner
of the Square proves to be part of the same system. Both the Square's
center and the Phi-point serve to divide the distance from K2 to Q in the
Golden Ratio.. We are looking at a diagram of a classic geometrical position.
The idea of the Cone's Key-circle is a nice addition
to our collection
of variations on the Golden Section. The diagram looks precise even
when blown-up as above, though in reality it is off by a couple of
thousandths of our unit. I suppose, what matters is we that we were
shown a simulation of another perfect design having to do with the
