Baudhayana
Baudhāyana, (fl. ca. 800 BCE)^{[1]} was an Indian mathematician, who
was most likely also a priest. He is noted as the author of the earliest Sulba Sutra — appendices to the Vedas giving rules for the construction of altars — called the Baudhāyana Śulbasûtra, which contained several important mathematical results. He is older than other famous mathematician Apastambha. He belongs to Yajurveda school.
His shrauta sutras related to performing to Vedic sacrifices has followers in some Smartha brahmins (Iyers)And some iyengars of Tamil Nadu, Yajurvedis or Namboothiris of Kerala, Gurukkal brahmins, among others. The followers of this sutra follow different method and do 24 thilatharpanam which his because of lord krishna who had done tharpanam on the day before amavasaya and they call themself as baudhayana amavasaya
This appears to be referring to a rectangle, although some interpretations consider this to refer to a square. In either case, it states that the square of the hypotenuse equals the sum of the squares of the sides. If restricted to rightangled isosceles triangles, however, it would constitute a less general claim, but the text seems to be quite open to unequal sides.
If this refers to a rectangle, it is the earliest recorded statement of the Pythagorean theorem.
Baudhayana also provides a nonaxiomatic demonstration using a rope measure of the reduced form of the Pythagorean theorem for an isosceles right triangle:

which is correct to five decimals.
Other theorems include: diagonals of rectangle bisect each other, diagonals of rhombus bisect at right angles, area of a square formed by joining the middle points of a square is half of original, the midpoints of a rectangle joined forms a rhombus whose area is half the rectangle, etc.
Note the emphasis on rectangles and squares; this arises from the need to specify yajNa bhUmikAs  i.e. the altar on which a rituals were conducted, including fire offerings (yajNa).
Apastamba (c. 600 BC) and Katyayana (c. 200 BC), authors of other sulba sutras, extend some of Baudhayana's ideas. Apastamba provides a more general proof of the Pythagorean theorem.
An altar is any structure upon which sacrifices or other offerings are offered for religious purposes, or some other sacred place where ceremonies take place.

The sutras of Baudhayana
The Sûtras of Baudhāyana are associated with the Taittiriya Śākhā (branch) of Krishna (black) Yajurveda. The sutras of Baudhāyana have six sections, 1. the Śrautasûtra, probably in 19 Praśnas (chapters), 2. the Karmāntasûtra in 20 Adhyāyas (chapters), 3. the Dvaidhasûtra in 4 Praśnas, 4. the Grihyasutra in 4 Praśnas, 5. the Dharmasûtra in 4 Praśnas and 6. the Śulbasûtra in 3 Adhyāyas^{[2]}.The Shrautasutra

Pythagorean theorem
The most notable of the rules (the Sulbasutras do not contain any proofs of the rules which they describe) in the Baudhāyana Sulba Sutra says:dīrghasyākṣaṇayā rajjuH pārśvamānī, tiryaDaM mānī,
cha yatpṛthagbhUte kurutastadubhayāṅ karoti.
 A rope stretched along the length of the diagonal produces an area which the vertical and horizontal sides make together.''
This appears to be referring to a rectangle, although some interpretations consider this to refer to a square. In either case, it states that the square of the hypotenuse equals the sum of the squares of the sides. If restricted to rightangled isosceles triangles, however, it would constitute a less general claim, but the text seems to be quite open to unequal sides.
If this refers to a rectangle, it is the earliest recorded statement of the Pythagorean theorem.
Baudhayana also provides a nonaxiomatic demonstration using a rope measure of the reduced form of the Pythagorean theorem for an isosceles right triangle:
 The cord which is stretched across a square produces an area double the size of the original square.
Circling the Square
Another problem tackled by Baudhayana is that of finding a circle whose area is the same as that of a square (the reverse of squaring the circle). His sutra i.58 gives this construction: Draw half its diagonal about the centre towards the EastWest line; then describe a circle together with a third part of that which lies outside the square.
Explanation:
 Draw the halfdiagonal of the square, which is larger than the halfside by .
 Then draw a circle with radius , or , which equals .
 Now , so this turns out to be which is about .
Square root of 2
Baudhayana i.612 (elaborated in Apastamba Sulbasutra i.6) gives this formula for square root of two: ''samasya dvikaraNI. pramANaM tritIyena vardhayet
tachchaturthAnAtma chatusastriMshenena savisheShaH.
