slide2
Phi
  • The golden number 1.618……
  • One way to find Phi is to consider the solutions to the equation
  • x = (1+√5)/2 ~ 1.618... or x=(1-√5)/2 ~ -.618...
  • and 1.618……is the golden number
slide3
We consider the first root to be Phi. We can also express Phi by the following two series

Phi =                                                       or Phi =

golden rectangle
Golden Rectangle
  • When we draw a rectangle that has sides A and B that are in proportion to the Golden Ratio

Golden rectangle.

  • Golden Rectangle

most pleasing rectangle to the eye.

slide5
Assume that rectangle ABCD is a Golden Rectangle. Hence, AD/AB =AE/ED
  • But, FE = AE, and so FE/ED= Phi
  • Hence, rectangle FCDE is a Golden Rectangle
slide6
If we connect the vertices of the regular pentagon, we can get two different Golden Triangles.
  • The blue and red one are all golden triangle.
slide7
If we take the isosceles triangle that has the two base angles of 72 degrees and we bisect one of the base angles, we should see that we get another Golden triangle that is similar to the first (Figure 1).
  • we can get a set of Whirling Triangles (Figure 2).

  • Strong and mysterious
  • By chance or bound to ?
  • Coincidence or regular pattern?

  • If we draw a line from the center A to the edge E, it will intersect with B, C, D
  • Then we can find that
  • And it fit golden ratio!!!
slide13
The ratio of the maple leaf’s width to it’s vein
  • The ratio of upper wings’ length to the lower one
  • They are all fit golden ratio
are u a model
Are u a model?
  • Length from head to belly button = x
  • Length from belly button to the ground = y
  • If y/x = 1.618……
  • Congratulation!!! You can be a model.
