The Great Pyramid of Giza was one of the first known examples of the Golden Ratio. The Egyptians created these sacred pyramids around 1560 BC, which demonstrate a right triangle.
Approximately between 500 and 432 BC, a Greek sculpture by the name of Phidias studied the Golden Ration. He applied this concept to the sculptures he created for the Athens’ temple, Parthenon.
Leonardo Da Vinchi created the painting names the Viturvian Man. The picture shows a man inside a circle with arms and legs out wide. This is demonstrating the lines of the golden ratio.
