**Pythagoras Theorem**,

One of the most important theorems starting from the seventh class till one has mathematics in studies.

It was in class 10 that I noticed a small caption in my Mathematics book specially in the page were Pythagoras theorem was given, It was

About Baudhayana a great mathematician,

It read this

“Baudhayana (800 .BCE) has written about Pythagoras theorem in his work Sulbha Sutra”

This made me search in detail about the Pythagoras theorem, which has given me an opportunity in knowing more about my country, Sanathana Dharma and also our ancestors and saints.

Baudhayana (800 BCE)

Was an Indian Mathematician who was a sage, Author of Sulbha Sutra, Shrauta Sutra and Dharma Sutra.

He was a master in performing Vedic Rites specially Yagnas or Yagas.

He was older than Apasthamba (450 bc) who is the author of Dharma Sutra whose work has been reproduced in English by oxford publishers – Dharma Sutras: The Law Codes Of Ancient India (Oxford Classics,1999).Baudhayana is accredited with calculating the value of Pi to some degree of precision.

**The Pythagoras Theorem in Sulbha sutra.**

The Sutra Says:

“dirghasyaksanaya rajjuh parsvamani, tiryadam mani,

Cha yatprthagbhuta Kurutastadubhayan karoti “.

A Rope stretched along the length of the diagonal (hypotenuse) produces an area which the vertical and horizontal sides make together.

Here DB is the hypotenuse.

**The Pythagoras Theorem** as stated by Pythagoras-The Greek mathematician (570-495 BC)

“In right angle triangle, the area of the square whose side is hypotenuse is equal to the sum of the areas of the squares whose sides are the two legs”.

The equation that we all use for our Calculations:

**“a²+b²=c²”.**

Pythagoras the Greek Mathematician is credited with the discovery and proof of this theorem.

It is true that he was the one who propagated it and rather found it in Greece. But in India it was earlier than that. It was used for constructing the Yagna bhumikas, the altar in which the yagas and the offerings are performed, They should have a special length and breadth and should be in the shape of rectangle or square i.e., (two triangles joint at their hypotenuse).

The above mentioned Sutra is the way the great master Baudhayana recognized the important Pythagoras Theorem. And also the disciples were thought with ropes as their measuring scales.

Baudhayana has not only given the Pythagoras Theorem in his Sulbha Sutra, But also given the approximate value of the square root of two, Circling of the square,ie. Finding a circle whose area is same as that of a square.(explanation given in wikipedia already).

This is elaborated by Apasthamba in his Sulbha Sutra.

Now there are even proofs that the Babylonian mathematicians have similar findings as that of Baudhayana and also we know that many of their calculations are also significantly used in mathematics.

Clay proofs of the Babylonian mathematicians.

The reason for such advancement is that only we, the Indians and the Babylonians had the concept of place value system. And this place value system needed the number 0 which is of course attributed to India (Aryabatta).

It was called **sunya i.e. empty void or nothing in Sanskrit** and was considered as a number by us while it was preceded by other numbers in Babylonian mathematics which was the only difference that changed the course of history and in fact everything in mathematics, Science and space.

Here I would like to add that Indians as well as Babylonians are pioneers in mathematics and the Babylonian relegion history suggests a lot of commonalities to that of Hindu religion.

This suggests that the Entire world starting from the oldest civilization of the Babylonians were followers of Sanathana dharma.

**More about Babylonians and their similarities with us and how the sanathana dharma was spread across the whole world in the upcoming articles.**

Claus, Did you write every one of these articles? IGU.

yup this 1 🙂 🙂 :)…..
