Geometry 7-1 Ratios and Proportions

... In these proportions, a and d are called the extremes, and b and c are called the means. In a true proportion, the product of the extremes is equal to the product of the means. That is, the cross products are equal. ...

The Golden Rectangle and the Golden Ratio

... this sequence with this series: 1+1/1·1. The third element is 1+1/1·1-1/1·2. The fourth is 1+1/1·1-1/1·2+1/2·3, and so on. This series was known long before I discovered it. The golden ratio can be represented as the simplest continued fraction (as shown below). ...
