The Golden Ratio was used a lot by Leonardo Da Vinci. Note how almost all of the dimensions of the room and the table in Da Vinci's painting "The Last Supper" were based on the Golden Ratio, which was known during Renaissance as The Divine Proportion.

The golden ratio is usually represented by Phi. It is approximately 1.618033988749895...
It is also equal to the square root of 5, plus 1 and then divided by 2. Almost everything in nature follows the pattern of the golden ratio. For example, all parts of the human body follow the rules of the golden ratio. The golden ratio can never be written as a regular fraction because it is an irrational number.

We'll start with the numbers 1 and 1. To get the next number we add the previous two numbers together. So now our sequence becomes 1, 1, 2. The next number will be 3. What do you think the next number in the sequence will be? If you said 4, then unfortunately you are incorrect. Remember, we add the previous two numbers to get the next. So the next number should be 2+3, or 5. Here is what our sequence should look like if we continue on in this fashion for a while:

1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, . . .

The golden ratio has been used by many artists. Some like Leonardo Da Vinci, and Piet Mondrian. If you look closely at their pai ntings you'll see how the golden ratio is in many parts of their work. The golden ratio is also most often denoted as phi(part of the Greek language.) The golden ratio is in many parts of this world; we just haven't discovered them yet.

Since the Renaissance artists have used the golden ratio in their art to proportion their work. Mostly they would porportion it around the golden rectangle. People study the golden ratiobecause of its unique portions.

The golden ratio is shown as the Greek letter phi.

the golden ratio equals 1.61803399

the golden ratio in a pentagon can be computed by ptolemy's theorom.

The golden ratio was used by Da Vinci when he drew Mona Lisa and many other pieces of his art.

the Egiptions were first to use math and used the golden ratio in their pyramids

sage is amazingly awesome

Brooke- The Golden Ratio is the pattern of most things in nature. It is used by many artists,arcitects,and many other things. It is represented by Phi a greek letter.

hurricanes use the golden ration says sage the wisest coolest skilliest person on the solar system

To get the golden ratio, you need to do a + b/b=a/b=The Golden Ratio.

The golden ratio is 1.6180339887. The golden ratio is often represented by a Greek letter that sounds like “phi.” Many architects and artists use it. The equation is this: Weird Greek letter that my keyboard can’t type = 1+ the square root of 5 over/divided by 2.

The approximate value of the golden ratio is 1.61803... but is more accuratly represented by (sqrt.of 5 + 1) / 2.

The larger number must be double the smaller number.
