WORLD HISTORY

Detailed explanation-1: -The ancient Egyptians solved this by measuring the pharaoh’s arm and this was called the “royal cubit”. Measuring rods of this length were made and builders could use these to make sure their buildings were the right size.

Detailed explanation-2: -Egyptian geometry refers to geometry as it was developed and used in Ancient Egypt. Their geometry was a necessary outgrowth of surveying to preserve the layout and ownership of farmland, which was flooded annually by the Nile river.

Detailed explanation-3: -The Great Pyramid uses simple 11:14 right-angled triangle geometry to simultaneously generate good approximations for and the golden ratio , outperforming all alternative geometries less complex than 986:1255, which would be more prone to erosion.

Detailed explanation-4: -We start our task of showing the connections between geometry, art, and architecture with what appears to be an obvious example; the pyramids, works of architecture that are also basic geometric figures. The pyramids were built in the lifetime of a single king, and were to help him in become immortal.

Detailed explanation-5: -Pyramids, the Pythagorean Theorem and Special Triangles The Pythagorean Theorem states that given a right triangle with sides of length a and b respectively and a hypothenuse of length c, the lengths satisfy the equation <math>a^2 + b^2 = c^2</math>.
