The document discusses the golden ratio and how it relates to cutting squares from golden rectangles. It then provides a list of measurements for analyzing facial features, with letters assigned to each measurement.

Who Is The Fairest Of Them All?
The golden ratio is a special number approximately equal to 1.6180339887498948482. We use the Greek letter Phi to refer to this ratio. Like Pi, the digits of the Golden Ratio go on forever without repeating. It is often better to use its exact value: 1 + 5 ------------ 2
If you have a Golden Rectangle and you cut a square off it so that what remains is a rectangle, that remaining rectangle will also be a Golden Rectangle. You can keep cutting these squares off and getting smaller and smaller Golden Rectangles.
