==== '''The Baudhāyana Theorem (Pythagorean Theorem)''' ====


The Sulba Sutras contain the first explicit statement of what is now known as the Pythagorean Theorem. The Baudhāyana Sulba Sutra <ref>[[Sulba_Sutra]]</ref> (1.48) states:

<blockquote>''&quot;The diagonal of a rectangle produces both areas that its length and breadth produce separately.&quot;''

</blockquote>

This was not a mere observation but a functional tool used to increase or decrease the size of an altar while maintaining its geometric proportions.


====  '''Discovery of Irrational Numbers''' ====


The Vedic requirement to double the area of a square led to the investigation of $\sqrt{2}$. The ''sutras'' provided an incredibly accurate rational approximation:

<math display="inline">\sqrt{2}</math> <math display="inline">\approx \ \frac{1}{1}</math> + <math display="inline">\frac{1}{3}</math> + <math display="inline">\frac{1}{3\  \times \ 4}</math> - <math display="inline">\frac{1}{3\  \times \ 4\  \times \ 34}</math>

This formula yields '''1.4142156.'''

==== '''Squaring the Circle and Geometric Algebra''' ====


The texts describe sophisticated procedures to transform one geometric shape into another without changing the total area. This includes:


* '''Squaring the Circle''': Creating a square with the same area as a circle.

* '''Circling the Square''': Constructing a circle equal in area to a square.

These tasks were required for rituals where different forms of fire (the square ''Āhavanīya'' and the circular ''Gārhapatya'') had to occupy equivalent symbolic and physical space.

दक्षिण = Semi Circular , आहवनीय = Square System , गार्हपत्य = Square in one system and Circular in other system.
