Le silence a régné dans la cour du château en 2020 en raison des contraintes sanitaires.
Espérons que la fête de Mézerville aura lieu en 2021 et que l’Association NAMUKA pourra
nous proposer un spectacle !
Golden Number and Geometry
The geometric construction of the Golden Number
• Let ABCD be a square
• O centre of AD
• An arc centered at O and radius OC intersects the prolongation of AD at F
• The segment AF represents the golden number
AF calculation
In the right angled triangle OCD:
If : AD =AB = BC = 1
So :
So :
The rectangle ABEF is called a “golden rectangle” because its sides are in the ratio of the golden number
Golden number and pentagon
The regular pentagon is a regular polygon with 5 sides inscribed in a circle and for which all the sides and all the angles have the same measuresments.
The angle between two consecutive sides equals 108°
Let ADC, ADF and AFC be the triangles
FD calculation
If DC = AD sin 18° + AC sin 18°
If DC = AD x 2sin 18°
DC = AD x 0,618
The ratio between a diagonal and one side of the pentagon is equal to the golden number.
The triangles AED and ADC are called “golden triangles” because their sides are in the ratio of the golden number
Another remarkable relationship:
Golden spiral
The sides of squares are a sequence of Fibonacci
1, 1, 2, 3, 5, 8, 13 ...
The face can be made from golden rectangles
