2.  Also known as The
Golden Mean, φ
(Phi), The Golden
Proportion
 Named after Phidias, a
greek sculptor that used
the golden ratio in his
sculptures.
 Phi ≈ 1.618

3.  Equation:
(a + b)/a = a/b ≈ 1.618

4.  If you look at the
sequence of fibonacci
numbers:
1, 1, 2, 3, 5, 8, 13, 21, 34
you will find that
1/1 = 1
2/1 = 2
3/2 = 1.5
5/3 = 1.6666...
8/5 = 1.6
13/8 = 1.625
21/13 = 1.61538...
34/21 = 1.61904...

5.  Resulting, as the numbers
settle, into the value called
the Golden Ratio which is
approximately 1.618

6. (history of the golden
rectangle and the golden
ratio)

7.  Draw a square.
 Extend two parallel sides.
 Draw a line from the
midpoint of one side of the
square to the opposite
corner.
 Using the line you just drew
as a radius, draw an arc
between the twoparallel
lines.

8.  Draw a perpendicular
line from between the
parallel lines from the
intersection of the arc on
the bottom line.
 You now have a golden
rectangle!

9.  Also Known as a
Fibbonacci Spiral
