THE REAL PYTHAGORAS
Recently, at the inauguration of the 102nd edition of the Indian Science Congress, union minister of science and technology, Dr Harsh Vardhan, mentioned that it was our scientists, from ancient India who discovered the Pythagoras theorem and we have always shared our knowledge with the whole world selflessly. This is something that each of us should be proud of. Right ? To my utter shock, many people including several scientists, objected and mocked the comment.
But Dr Harsh Vardhan is absolutely right !!
Ancient Indian mathematicians discovered the Pythagoras theorem. This might come as a surprise to many, but it’s true that Pythagoras theorem was known much before Pythagoras and it was Indians who actually discovered it at least 1000 years before Pythagoras was born!
It was Baudhayana who discovered the Pythagoras theorem. Baudhayana listed Pythagoras theorem in his book called Shulba Sutra (800 BCE). It is also one of the oldest books on advanced Mathematics. The word ‘Shulba’ in Sanskrit means rope or cord. Hence Shulba Sutra was a book of geometry. The actual shloka (verse) in Baudhayana Shulba Sutra that describes Pythagoras theorem is :
dīrghasyākṣaṇayā rajjuḥ pārśvamānī, tiryaḍam mānī,
cha yatpṛthagbhūte kurutastadubhayāṅ karoti.
The above shloka can be translated as – A rope stretched along the length of the diagonal produces an area which the vertical and horizontal sides make together.As you see, it becomes clear that this is perhaps the most intuitive way of understanding and visualizing Pythagoras theorem (and geometry in general) and Baudhāyana seems to have simplified the process of learning by encapsulating the mathematical result in a simple shloka in a layman’s language.
Though, Baudhayana was not the only Indian mathematician to have provided Pythagorean triplets and proof. Apastamba also provided the proof for Pythagoras theorem, which again is numerical in nature but again unfortunately this vital contribution has been ignored and Pythagoras was wrongly credited by Cicero and early Greek
mathematicians for this theorem. Baudhayana presented geometrical proof using isosceles triangles so, to be more accurate, we attribute the geometrical proof to Baudhayana and numerical (using number theory and area computation) proof to Apastamba.
Apart from the two, another ancient Indian mathematician called Bhaskara later provided a unique geometrical as well as numerical proof of the Pythagoras theorem, which works for all types of triangles (not just isosceles as in some older proofs).
Mathematicians and scientists from all over the world are now accknowleging and accepting the accompliments of ancient Indians in the fields of maths and science.
Now its our turn to do the same !!

You are discussing an extremely important matter. Great job.
Before straight to the answer, I recommended you to look about the base line or foundation of advanced mathematics we are using right today.

Thanks . Reblogged
Asian people used Pythagaras theory for make rectangle forhouse construction.In that period Pythagaras not born also.They used 3×3+4×4=5×5.
