What is known as the Baudhayan theorem?

Baudhayan Sulv Sutra (1000 BC) is today known as the Pythagoras theorem, which states that in a right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides. In Baudhayan theorem, this has been expressed as follows: in a Deerghchatursh (triangle), the chetra (square) of rajju (hypotenuse) is equal to the sum of squares of the parshvamani (base) and triyangmani (perpendicular line). It is amazing to note that the Pythagoras theorem was known in our country as far back as 1000 BC.
