s ratio is more easily recognized if we consider its reciprocal .7888. Four root-five rectangle reciprocals equal the ratio 1.7888, .4472 multiplied by four. .7888, therefore, is four root-five rectan- gles minus one. It is .a beautiful shape and may be obtained readily from the whirling square… … The area AB in Fig. 23 is composed of two squares and two root-five rec- tangles, or the ratio 2.8944, i. e., 1.4472 multiplied by two; .691 divided into 2.000. The fraction is not quite .691, but this number is sufficiently close for all practical purposes. BC and CD are two equal areas each…
