I don't understand exactly what it is saying that I have to prove. I tried making the base triangle and 3,4,5 triangle and then going from there, but I don't know how they are forming the other triangles. If you could help me in any way I would greatly appreciate it.

Extractions: Né dans l'année 836 APR. J.C. à Harran (Turquie présente). Comme le nom indique il était un membre de la secte Sabian fondamentalement, mais le grand mathématicien Muhammad Ibn Musulman Musa Ibn Shakir, il a impressionné par ses connaissances des langues, sa grande capacité scientifique, ce qui lui avalu d'intégrer le groupe scientifique à Bagdad qui était patronné par les Califes Abbasid. Là, il a étudié sous la direction des frères Musa. Thabit a contribué à plusieurs branches de science, particulièrement les mathématiques, l'astronomie et la mécanique, en plus de la traduction d' un grand nombre de travaux des grecs en arabe. Plus tard, il a été patronné par le Calife Abbasid al-M'utadid. Après une longue carrière, Thabit est mort à Bagdad en 901 APR. J.C.

Extractions: Free Web site hosting - Freeservers.com THABIT IBN QURRA (836-901 A.D.) Thabit Ibn Qurra Ibn Marwan al-Sabi al-Harrani was born in the year 836 A.D. at Harran (present Turkey). As the name indicates he was basically a member of the Sabian sect, but the great Muslim mathematician Muhammad Ibn Musa Ibn Shakir, impressed by his knowledge of languages, and realising his potential for a scientific career, selected him to join the scientific group at Baghdad that was being patronised by the Abbasid Caliphs. There, he studied under the famous Banu Musa brothers. It was in this setting that Thabit contributed to several branches of science, notably mathematics, astronomy and mechanics, in addition to translating a large number of works from Greek to Arabic. Later, he was patronised by the Abbasid Caliph al-M'utadid. After a long career of scholarship, Thabit died at Baghdad in 901 A.D. Thabit's major contribution lies in mathematics and astronomy. He was instrumental in extending the concept of traditional geometry to geometrical algebra and proposed several theories that led to the development of non-Euclidean geometry, spherical trigonometry, integral calculus and real numbers. He criticized a number of theorems of Euclid's elements and proposed important improvements. He applied arithmetical terminology to geometrical quantities, and studied several aspects of conic sections, notably those of parabola and ellipse. A number of his computations aimed at determining the surfaces and volumes of different types of bodies and constitute, in fact, the processes of integral calculus, as developed later.

http://www.loqmantranslations.com/ArabicFacts/ArabTranslators.html

Extractions: Consulting Translators Contact Us Abu Zayd Hunayn ibn Ishaq al-Ibadi (808 - 873) Hunayn ibn Ishaq is most famous as a translator. He was not a mathematician but trained in medicine and made his original contributions to the subject. However, as the leading translator in the House of Wisdom at one of the most remarkable periods of mathematical revival, his influence on the mathematicians of the time is of sufficient importance to merit his inclusion in this archive. His son Ishaq ibn Hunayn, strongly influenced by his father, is famed for his Arabic translation of Euclid's Elements. Hunayn's father was Ishaq, a pharmacist from Hira. The family were from a group who had belonged to the Syrian Nestorian Christian Church before the rise of Islam, and Hunayn was brought up as a Christian. Hunayn became skilled in languages as a young man, in particular learning Arabic at Basra and also learning Syriac. To continue his education Hunayn went to Baghdad to study medicine under the leading teacher of the time. However, after falling out with this teacher, Hunayn left Baghdad and, probably during a period in Alexandria, became an expert in the Greek language. Hunayn returned to Baghdad and established contact with the teacher with whom he had fallen out. The two became firm friends and were close collaborators on medical topics for many years.

Arabic Numerals

http://www.arabicnumerals.cwc.net/

Extractions: By M Erhayiem The IBM World Book Encyclopaedia raises the question as how the Arabic Numerals originated (!?) as appeared in an article contributed by Nadine L. Verderber, Ph.D., Prof. of Mathematics, Southern Illinois Univ., Edwardsville. The article states, as such, "Scholars do not know how Arabic numerals originated." "The Hindus developed the zero sometime after A.D. 600." The World Book Multimedia Encyclopaedia has largely ignored the work of the Scientists during the Islamic and the Arabic medieval era. The contributions of the Muslims and Arabs in the field of Mathematics were very significant. The great Harvard historian of science, Professor George Sarton wrote in his monumental Introduction to the History of Science[4]: "From the second half of the 8th to the end of the 11th century, Arabic was the scientific, the progressive language of mankind... When the West was sufficiently mature to feel the need of deeper knowledge, it turned its attention, first of all, not to the Greek sources, but to the Arabic ones." O'Connor and Robertson[2] published various articles about the contribution of those forgotten brilliance. Muhammad ibn Musa al-Khawarizmi Yaqub ibn Ishaq al-Kindi (801-873 A.D.), a Philosopher and Mathematician, who wrote many works on arithmetic, including: the numbers, relative quantities, measuring proportion and time, and numerical procedures. He also wrote on space and time.

Extractions: First Half of Tenth Century The overwhelming superiority of Muslim culture continued to be felt throughout the tenth century. Indeed, it was felt more strongly than over, not only the foremost men of science were Muslims, but also because cultural influences are essentially cumulative. By the beginning, or at any rate by the middle of the century, the excellence of muslim science was already so well established, even in the West, that each new arabic work benefited to some extent by the prestige pertaining to all. To be sure, other languages, such as Latin, Greek, or Hebrew were also used by scholars, but the works written in those languages contained nothing new, and in the field of science, as in any other, when one ceases to go forward, one already begins to go backward. All the new discoveries and the new thoughts were published in arabic. strangely enough, the language of the Qur'an had thus become the international vehicle of scientific progress.

Extractions: The whole ninth century was essentially a Muslim century. This more clear in the second half than of the first, since all the scientific leaders were Muslims, or at any rate were working with and for Muslims and wrote in Arabic. Cultural Background Abbasid Caliph Al-Mutawakkil (847-861) continued to protect men of science, chiefly the physicians, and he encouraged the school of translators headed by Hunain ibn Ishaq.
