Transcript of The Golden Ratio and Great Pyramids of Giza

Can you find the golden
ratio in the great pyramids
of Giza and in nature? By Lexie Kavanagh 7G To find the Golden ratio in the great pyramid of Giza, you have to find the measurements of: half the base, which is 115.18m. The sloped height of the pyramid is 186.54m. so then to find the ratio, you have to divide the sloped height by half the base. (186.54 / 115.18= 1.61.) Which is the Golden Ratio. Great Pyramid Of Giza Golden Ratio The Golden Ratio is a rectanular/triangular/circular or spiral shape that is pleasing to the human eye itself. For it to become the golden ratio, its measurements have to add up to 1.6 in either m, mm or cm. It is found in art, nature, advertising etc. For it to become a golden ratio shape,(for a rectangle)- it has to be divided by it's two sides. Length and width. To find the ratio of a square based pyramid, you have to divide the sloped height by half the base. if it turns out to be 1.6, then it is the golden ratio. What is the Golden Ratio? The Great Pyramid of Giza is found in Egypt. It was said to be built by Egyptians in ancient times. They tried to build many perfect pyramids to bury their pharoah in, once he had died. Some pyramids turned out to have curved faces, instead of straight.Which wasn't pleasing to the eye. But, the Great Pyramid Of Giza was the perfect pyramid with exact degree sides and, had the Golden Ratio.
Every new cell created in a plant or flower, grows in some kind of pattern. Some cells fit to make the golden ratio. In the picture above, every small part of the flower is a cell. The spiral happens naturally because each new cell is formed after a turn. New cell, then turn, then another cell, then turn and so on. Golden Ratio In Nature The Great Pyramid Of Giza In the picture above, it shows that this shell created from nature fits perfectly into the spiral from the Golden Ratio. Many other nature created items fit to the Golden Ratio whether in the sea or dry land. Nature and Golden Ratio During this investigation, I found out that the Golden Ratio is pleasing to the eye itself and that even in Ancient times they used the Golden Ratio. I also found out that the Golden Ratio is found almost everywhere on this Earth. For example, art, nature, advertising, constructing and many more. Reflection: (cc) photo by theaucitron on Flickr
