Phi, The Fibonacci Spiral, Golden Rectangle, Pentagons, Vesica Piscis & a Golden Quadratic

6/21Doing construction I also realize now that to construct a heptagon or Septagon (7 sides) you would use phi over 2 (see my heptagon construction vide). Because you make the egg of life (vesica Pisces) and use half of the distance of phi. This will make 7 congruent sides and a heptagon.

The proportions of the golden ratio - Phi (pronounced fye) are the proportions used in the fibonacci spiral, the golden rectangle, a pentagon, and are even in the perpendicular bisector (the Vesica Pisces it can be called - contenting the roots 1-5).

We use the proportions of phi to build things with efficiency, strength, and balanced proportions that are useful and appealing to the eye.

We explore the places we see Phi, including a special polynomial - the quadrilateral X^2-X-1 contains the roots or solutions of phi and the negative inverse of phi -

Incidentally, the "Jesus Fish" is made by the Vesica Pisces. Which is a perpendicular bisector containing the ratio Phi
