Types of Quadrilaterals

There are six basic types of quadrilaterals:
1.  Rectangle
Opposite sides of a rectangle are parallel and equal.  All angles are 90º.

2.  Square
Opposite sides of a square are parallel and all sides are equal.  All angles are 90º.

3.  Parallelogram
Opposite sides of a parallelogram are parallel and equal.  Opposite angles are equal.

4.  Rhombus
All sides of a rhombus are equal and opposite sides are parallel.  Opposite angles of a rhombus are equal.  The diagonals of a rhombus bisect each other at right angles.


5.  Trapezium
trapezium has one pair of opposite sides parallel.  A regular trapezium has non-parallel sides equal and its base angles are equal, as shown in the following diagram.

6.  Kite
Two pairs of adjacent sides of a kite are equal, and one pair of opposite angles are equal.   Diagonals intersect at right angles.  One diagonal is bisected by the other.

4.  Rhombus
All sides of a rhombus are equal and opposite sides are parallel.  Opposite angles of a rhombus are equal.  The diagonals of a rhombus bisect each other at right angles.


5.  Trapezium

Burj al Arab


$650 million




It is use like an Hotel







197.5 m


321 m


60 floors (202 suites)


History and interesting things
On the hotel roof is a heliport, which was used as a tennis court for advertising involving Roger Federer and Andre Agassi, but that, despite what many believe, is not used as field tennis.
The interior decoration of the building was carried out by Chinese designer Khuan Chew. The instructions el Jeque of Dubai gave Chew for the design of the suites and atrium were hit and innovate. Khuan and his team used large quantities of marble, velvet and leaflets of ore for decorate. Six months before the inauguration, Sheikh visited the hotel to give his opinion. The majesty of the suites met his expectations of luxury and grandeur show, but seeing the painting of a minimalist atrium, failed. The decorator had to redesign the look of the lobby, adding bright colors on the roof, dancing fountains, a spectacle of colored lights and giant aquariums.
The Prices of the rooms varies between $ 2,500 and $ 40,000 per night. The design of the suites unites East and West. The bathrooms are with mosaics. The Royal Suite, is valued at $ 137,716 per night, is in the world ranking of the 15 most expensive hotel rooms, done by CNN Go in 2012.
The Burj Al Arab has nine restaurants, among them the Al Mahara -under the sea, offering an underwater view through a stained glass window as aquarium and Al Muntaha, located 200 meters high, and allowing a view of the city of Dubai.
The clients have the ability to request a Rolls Royce Silver Seraph for transport. The cars were imported from Britain. Clients can also request a helicopter that goes straight to the hotel located on the helipad

This building since I knew about it, I loved it. I like this entire beautiful hotel and the most incredible thing is that is on a small island on the beach. My favorite part of the hotel is that has some restaurants with gorgeous views. One of the restaurants is over the sea so you can see the sea wildlife. And another restaurant you can see a panoramic view of Dubai.

TECHNOSPHERE OF DUBAI by Sara Zapico Linares 3rd ESO C


The concept of this iconic building for the Techno sphere of Dubai, is a building which will reflect the state of Planet Earth in the current and future times. Planet Earth embodies the very essence of the ecosystem that we live in.

The Techno sphere has several key technology systems and architectural spaces that will 
enable the building to generate a self breathing environment as well as generate electricity 
from solar power to supplement the energy needs of the building.



The Aldar HQ building is located in Raha Beach, a new city on the outskirts of Abu Dhabi.
Its architectural style is called structural expressionism also known as High-Tech modernism.
This style is an advanced modernism in which buildings display their structural elements inside and out. Structures in this style tend to have a metallic appearance.
The Aldar HQ is the first circular skyscraper in the world. The construction was completed using a steel diagonal grid to sustain the circular shape and then covered with glass panels.
Marwan Zgheib decided to create a simple building that would possess the calm and ideal   beauty but also have expressive power.


He is an Architect an Interior Designer and a Technologist with a love for Design and Art. He runs his own design company James Law Cybertecture. He also is a Young Global Leader of World Economic Forum a founder of NGO Cybertecture for Humanity. On most of his free time e runs a Young Architect Program for kids. He is an occasional TED speaker and teach part time in universities in Hong Kong. Combining technology and architecture, Law has designed some of the most innovative projects in the world, including the world's first artificial intelligent media laboratory for the Hong Kong government. 
Born in Hong Kong and raised in the United Kingdom from the age of nine, Law began to discover his talents in architecture when he was just 7-years-old.
His passion for architecture eventually led him to study the discipline at the University College London, under renowned visionary architect Peter Cook. Upon graduation in 1992, Law took up his first job as an architect at the firm of prestigious Japanese architect Itsuko Hasegawa in Tokyo in 1994. 

Following this, Law moved back to Hong Kong in 1997 to take up a position as the Director of Gensler International, one of the largest design firms in the world, and to focus on technology projects.


In my personal opinion, this sphere is a huge and innovating idea because it is an eco-friendly building which helps to reduce the amount of pollution we create regularly, and show us that, if we were able to produce all buildings yhis way, we will conserve our world for longer

Catedral Basílica Menor Nossa Senhora da Glória

The cathedral of Maringá is a Roman Catholic cathedral located in downtown Maringá, Paraná, Brazil. The architect was José Augusto Bellucci, he started it in 1958 and he finished it in 1975.

The architect José Augusto Bellucci was inspired by the Soviet sputnik satellites when he designed the cathedral's modernist, conical shape. The design was idealized by the archbishop Dom Jaime Luiz Coelho.

The cathedral is madre up pf glass, stone, marble and concrete.
It is the tallest church in South America and the 16th in the world. It´s height is 125m.
It´s architectural style is futurism.

In our opinion this cathedral has a very original desing and it´s very huge.

Golden ratio in Human face

Phi ( Φ = 1.618033988749895… ), most often pronounced fi like “fly,” is simply an irrational number like pi ( p = 3.14159265358979… ), but one with many unusual mathematical properties.

The design of Human face is based on a “Golden Ruler, a ruler composed of golden ratios within golden ratios. It has long been known that the Golden Section, (also Golden Ratio or Divine Proportion), appears in certain proportions of living organisms.

Leonardo Da Vinci has long been associated with the golden ratio.Da Vinci created the illustrations for the book “De Divina Proportione” (The Divine Proportion) by Luca Pacioli. It was written in about 1497.In the book, Pacioli writes of mathematical and artistic proportion, especially the mathematics of the golden ratio and its application in art and architecture.

It was a project made by Étienne-Louis Boullée in 1784, to honour Isaac Newton’s discoveries.
It’s a neoclassical building, similar to Greek and Roman mausoleums.
 Étienne-Louis Boullée was born in Paris, in 1728 and died in 1799. He was a visionary architect, theorist and teacher. He wanted to be a painter, but, following the wishes of his father, he turned to
architecture. He opened his own studio with 19 years old. He designed several mansions in Paris in the 1760s and ‘70s, like the Hôtel de Brunoy. He teached in the Ecole Nationele des Ponts et Chaussées and in the Académie Royale d’Architecture in Paris. His works were innovative, from the Neoclassicism.


Although it has never been built the drawings were engraved and circulated between some of the most important architects of the era. They said he was a megalomaniac and until the twentieth century its work wasn’t published. Nowadays the drawings and plans are in the National Library of Paris.


The cenotaph (a monument dedicated to the memory of someone, but with no body preserved inside) is a large sphere of 150 meters high on a circular base and covered by cypresses. From the outside, you can only see half the sphere, supported by two cylinders.

The building represents the land and Newton’s discoveries. Its access is in the base and, no matter the size, only a small area in the base can be occupied. Its surface is perforated, so that sunlight can enter during the day and create a picture of the night sky. During the day a great artificial light in the centre of the sphere represents the daytime. Light represents Newton, lighting the knowledge of mankind.


It is a huge and very simple building. It hasn´t got any unnecessary decoration and it expresses its function. For me it’s gorgeous and well balanced.

La Geode is a mirror-finished geodesic dome that holds an Omnimax theatre in Parc de la Villette at the Cité des Sciences et de l'Industrie (City of Science and Industry) in the 19th arrondissement of Paris,

La Géode was designed by architect Adrien Fainsilber and engineer Gérard Chamayou. The geodesic dome is 36 metres (118 ft) in diameter, composed of 6,433 polished stainless steel equilateral triangles that form the sphere that reflects the sky. It stands on a reinforced concrete based, which is attached to Cité des Sciences et de l'Industrie, the largest science museum in Europe. La Géode officially opened on May 6, 1985. After a similar venue located in La Défense closed in 2001, La Géode became the only spherical building in the Île-de-France region of France. It cost 130 million French francs to build.

Before the name "Géode" was selected, other names were proposed, including humorous suggestions such as "Bouboule", "Irma", "Minouchette", "Double Zéro", and "Zézette".


Movies are projected in IMAX format on a giant hemispherical screen that covers 1,000 square metres (11,000 sq ft). The auditorium is fitted with a 12 point sound system with four large subwoofers that deliver 210,000 watts in surround sound designed by Cabasse. The IMAX films, presented in high definition and Géode 3D-relief, feature science, nature, and travel documentaries, short and long feature-length films, and high definition animated subjects. It also presents satellite concert events, including live broadcasts of the Metropolitan Opera from New York City.
