In the rhombic triacontahedron the dihedral angle between anytwo adjacent rhombi is 144, which is twice the isosceles angle of a golden triangle and four times its most acute angle. 91 Some the price of inequality essay specific proportions in the bodies of many animals (including humans 92 93 ) and parts of the shells of mollusks 5 are often claimed to the 13 articles of faith be in the golden ratio. So the angles of the golden triangle are thus 36-72-72. This result is a straightforward consequence of the intersecting chords theorem and can be used to construct a regular pentagon, a construction that attracted the attention of the noted Canadian geometer. In fact, it is probably fair to say that the Golden Ratio has inspired thinkers of all disciplines like no other number in the history of mathematics. De Divina Proportione contains illustrations of regular solids by Leonardo da Vinci, Pacioli's longtime friend and collaborator; these are not directly linked to the golden ratio. 3 19 Timeline Timeline according to Priya Hemenway: 20 Phidias (490430 BC) made the Parthenon statues that seem to embody the golden ratio.

"It is well known that the eyes take in information more efficiently when they scan side to side, as opposed to up and down.And these rhythms are at the very root of human activities.Design Some sources claim that the golden ratio is commonly used in everyday design, for example in the shapes of postcards, playing cards, posters, wide-screen televisions, photographs, light switch plates and cars.
