### Proportionality in architecture

Architects have always used the ratio in their work, and the history of the use of ratios in the architecture dates back to many centuries ago. In Romanian and Greek temples and even mosques and churches.

And also also to the creation of God Almighty and where we are when we look at the human body architecture, we find that the golden ratio in particular is repeated often in the lengths of the human members of each lineage.

Definition and proportionality ratio: the ratio in mathematics: numerical quantities are expressing mathematical relationship between two or more parts of a complete set. And breakage formula used to express the concept of percentage, such as the proportion of the length of the rectangle to be displayed in the architecture: ratios is the consistency of the configuration and architectural vocabulary formative each other dimensions and between each of them and the composition as a whole.

Ratios functional and aesthetic aspects of the construction of the facility associated with architectural also helps to show the specific architectural character of the building structure and formative.

Proportionality in architecture: a process designed to adjust and balance the architectural configuration according to a specific principle that the architect is usually not able at the beginning of the design interaction adjust fit shapes directly where treated initially logic formative year, depending on experience and sense of aesthetic comes scrutiny ratios and balance training in advanced stages .

Can not say for sure that the ratio of what is beautiful and harmonious proportion permanently where they can rate the graceful and acceptable to be in place and unacceptable in another place and therefore a lot of designers rely while addressing formative ideas on their ability sensual and artistic taste to reach the dimensions required while some resort to mathematical and engineering ways to make sure relations and corrected if necessary.

Some researchers are looking for laws and pacemakers proportionality in nature, in human height and shape, in ancient and other architectural masterpieces, hence Enter Fterovios module term in Architecture (Module), the giant of the Renaissance, Leonardo da Vinci has Jaddaola prepared for proportionality classic relations after his analysis of the average human body and compared with the average human height also pointed out that the mathematical relationships help to give a beautiful proportions of the elements of the technical configuration. Topics ratios and proportionality has become the focus of attention of researchers and scholars, especially the great architect Le Corbusier through his book and his regime standard (Modiolar).

Golden Ratio sector Golden: is the ratio that we get when we divide the line segment into two unequal and so are the largest part to the younger equal to the ratio of the length of line segment to the length of the bulk rate, and to express this mathematically the relationship we write: A: B = (A + B): A means that: A / B = A + B / AA / B = 1 + B / A imposition of a / B = XX = 1 + 1 / X X2 = X + 1 and solving this equation of the second degree, we find that the root Mujib equation: X = 1.618 either inverse relationship (negative root of the equation): 1 / X = 0.618
