According to historical documents, it is challenging to establish whether a proof of Th¯abit’s theorem exists based exclusively on equidecomposibility, as in the case of the Pythagorean and Pappus theorems. This article presents the corresponding proof. Key Words: Euclidean geometry, generalization of Pythagorean theorem, equide-
THABIT IBN QURRA AND THE PYTHAGOREAN THEOREM By Robert Shloming, Brooklyn College, Brooklyn, New York DURING the Dark Ages of Western Europe, Islam was very much mathemati cally alive. The Arabs were able to solve the most difficult problems of Archimedes and Apollonius at a time when Latin mathematical knowledge was at a level
The proof of Thabit’s generalization is identical to one of the standard ways of proving the theorem of Pythagoras using similar triangles, and provides a very accessible generalisation with which to challenge learners.
His work in mathematics also includes original treatises, with contributions in the many areas of geometry and number theory. His original contributions include proofs of the Pythagorean theorem, a proof of Menelaus's theorem, proofs of Euclid's fifth postulate, and work on composite ratios.

In http://math.ucr.edu/~res/math153/history05f.pdf we presented a generalization of the Pythagorean Theorem due to Pappus. As with nearly all fundamental theorems, there are many possible generalizations and analogs, and here we are concerned with one which is due to Thabit ibn Qurra.
4 Οκτ 2019 · Here in this article, I will show a new long proof of the theorem. Firstly, I will prove a formula which will help us to know the length of a square inscribed in a right triangle. The square...
