One of the most amazing architecture made during the Renaissance was built in Italy by a man called Filippo Brunelleschi. Brunelleschi made the Santa Maria del Fiore cathedral in Florence, Italy. It took him 16 years to create and used mainly only two materials marble and brick. The cathedral finished its construction on the 9th of September 1296. Many experts do not understand the logic of how it was built. But what we do know is that Brunelleschi invented many new techniques to produce such an amazing cathedral. The Basilica di Santa Maria del Fiore or Florence Cathedral is the cathedral church of Florence, Italy. The basilica was designed by Arnolfo di Cambio with the dome by Filippo Brunelleschi. The bell tower was designed by Giotto. The outside is decorated with marble panels in green and pink bordered by white. The building was begun in 1296 and was finished in 1469, except for the decoration. The facade (the main front) was decorated between 1876 and 1903. The dome, which is built of bricks with stone ribs, is one of the biggest in the world.
From about 1464 the members of the Wool Guild wanted to have twelve statues of people from the Old Testament of the Bible carved for the Florence Cathedral. These statues were to go on the buttresses all around the outside walls, high up near the roof.

Sainte Chapelle
La Sainte-Chapelle () is a Gothic chapel found on the Île de la Cité in the heart of Paris, France. This chapel is a perfect example of the "rayonnante" period of Gothic architecture. The chapel was designed by architect, Pierre de Montereau.
La Sainte-Chapelle was built in six years (1242-1248). It was consecrated in 1248. The building was designed to house the relics of the Passion, especially the Crown of Thorns. King Louis IX had acquired this Crown from Emperor Baudouin II in 1239. The possession of this relic put France in the forefront of Latin Christendom.
Other relics were brought from Byzantium over the next two years. These relics were kept in the Saint-Nicholas Chapel until a more appropriate place could be prepared. During the French Revolution, the choir stalls and the rood screen of Sainte Chapelle were destroyed. The spire was torn down and the relics sent elsewhere. Restoration of the chapel was undertaken in 1846. The chapel was returned to its former splendor with this restoration.
The stained glass windows of the chapel are its chief glory. They tell the story of humankind from the Creation to the Redemption of the world through Jesus Christ. These windows contain 6,458 sq. ft of glass. Two thirds of the glass are original. Each window is divided into lancets. These lancets must be read from left to right, working from the bottom up. They were restored in the 19th century.

Equilateral triangle
In geometry, an equilateral triangle is a triangle where all three sides are the same length and all three angles are also the same and are each 60°.
If an altitude is drawn, it bisects the side to which it is drawn, in turn leaving two separate 30-60-90 triangles
Denoting the common length of the sides of the equilateral triangle as "a", we can determine using the Pythagorean theorem that:
Denoting the radius of the circumscribed circle as "R", we can determine using trigonometry that:
Many of these quantities have simple relationships to the altitude ("h") of each vertex from the opposite side:
In an equilateral triangle, the altitudes, the angle bisectors, the perpendicular bisectors and the medians to each side coincide.
Three kinds of cevians are equal for (and only for) equilateral triangles:
Every triangle center of an equilateral triangle coincides with its centroid, which implies that the equilateral triangle is the only triangle with no Euler line connecting some of the centers. For some pairs of triangle centers, the fact that they coincide is enough to ensure that the triangle is equilateral. In particular:
For any triangle, the three medians partition the triangle into six smaller triangles.
