Transcript of The Golden Ratio Used In Architecture

The Golden Ratio Used In Architecture The Golden Ratio is approximately 1.618.
The Golden Ratio is used in many things
because it is said to be attractive like: most T.V screens, The Parthenon, paintings and the Great Pyramid. The Golden Ratio is calculated by dividing the shorter side with the longer side. If the answer equals 1.618 you have an exact Golden Ratio Where is the Golden Ratio In The Great Pyramid More Detailed Information On The
Great Pyramid's use of the Golden Ratio Golden ratio used in
the great pyramid Golden ratio used in the
Parthenon The Golden Ratio is used in the Great Pyramid. As you can see in the picture below the Golden Ratio. Each side of the triangle intersects at the ground with a certain angle to be exact which is a little less than 52 degrees. Slanted height divided by half the base = the
Golden Ratio in the Great Pyramid. Today the
measurements of the Great Pyramid are very inaccurate because of erosion. But the
measurements are still very close to the Golden
Ratio. The Giza Pyramid The Equations of
The Great Pyramid Since the equation for the golden ratio in the great
pyramid is slanted height divided by 1/2 the base. Still Puzzled: Here is a video on the
Golden Ratio Slanted Height = 186.369m
Base Length = 230.363m

= (base) divided by 2
= (230.363) divided by 2
= 115.182
= (slant height) divided by (half base)
= (186.369) divided by (115.182)
= 1.61803927697036 More Architecture
That Uses The Golden
Ratio Relation's of The Golden Ratio The Golden Ratio is very similar to the Fibonacci numbers. The
first signs of the Golden Ratio is from an Indian text
from 1200BC. Fibonacci made something called the Fibonacci
Spiral which is a spiral which relates to the Golden Ratio.
Fibonacci numbers go in this order: 0,1,1,2,3,5,8,13,21,34,55
and the list goes on. Fibonacci blocks were also created with the Fibonacci numbers as you can see in the picture below. The Golden Ratio is also used in the Chartres
Cathedral. Medieval builders copied off the
Greeks because they had good geometric structure. Like the greeks many parts of this building have the Golden Ratio in it. Reflection I think that the Egyptian's knew about the Golden Ratio because it isn't physically possible that the Egyptians could make a Pyramid with the Golden Ratio but be so close. It is also proven that the Golden Ratio was used in an Indian text 1200BC. Which exactly proves that in that era they knew what it was, but with the Egyptians use of the Golden Ratio is still unknown.
