# Islamic Geometry

The golden age of Islam during 900-1100 A.D

#### Transcript of Islamic Geometry

Importance of Geometry Geometry flourished during the Islamic Golden age between 900 AD and 1100 AD. It proved muslims had skill and potential in what they did, as proof there are the beautiful examples of there calligraphy and architectural mosques. Time of Islamic Geometry The Golden Age was from 900 to 1100 AD but the exact time when geometry flourished was around 750 AD because of the many famous Muslim scholars who worked in the field of geometry. Geometry has shaped our world in many different ways. For example, you can see the many churches and some buildings which have a certain architectural design that was inherited from the muslims during the Golden Age of Islam. The Influence of geometry on the world Repeat Unit of design, or in other words a tessellation The Islamic design of art or a Islamic tessellation usually is related to plants, animals, and caligraphy. Instead of Humans being used in art as drawings, muslims don't because they are forbidden in their religion. Examples of buildings decorated with Islamic geometry in architecture and the tesselations Jerusalem's Dome of the Rock, built in 691-692 Built in Iran Egypt Iran Iran Tokyo, Japan Lahore, Pakistan Iran Iran Alexandria, Egypt Islamic Geometry Malaysia Russia Iran Features of a mosque usually decorated Domes Walls Entrances The geometry used in the Taj Mahal The Taj Mahal has many examples of geometry.The minarets which are around the four corners of the Taj Mahal are 137 feet high and are cylindrical columns . The main structure is cubical but very large indeed. The circle at the base arches upward to create the famous onion dome. The doorways are rectangular in design with semi-octagonal angles. The room that the tombs are placed in is octagonal. As you look at the Taj Mahal, there are multiple lines of symmetry. The entire building is laid out in quadrilaterals, which turn out to make a equal and fitting effect to the whole building. Importance of Geometry in the world Geometry and art are clearly important to our world, they give shape to buildings, and design so they are not completely plain. They are found in more than just buildings and mosques, but in many things such as pottery, rugs walls, statues, plates, tables, chairs, even the weapons used at the time such as swords! Muslim Contributors to the field of Geometry Nasir Al-Din Al-Tusi was the first man that proved Euclids theory lacked parallels.

Thabbit ibn Qurrah devoloped a new way to divide the angle into three equal parts.
