The most widely used geometric theorem is what we call2day as ``Pythagoras theorem`` And It's named after Pythagoras !

But many of us (not2count NCERT ?) know that the same theorem was already discovered 600yrs (atleast)before him in INDIA

Yes, this was by Boudhayan, the author of the oldest SULVA SUTRA ! Plz take a note what he says :=

"Dirghachaturasrasyakshyana . . . . Kurutastadubhayam karoti " which means, the area made by a square,on the hypoteneous

of a rectangle, equals 2the area of the squires made on its sides separately" [bo.sul.sutr-1\48], [ap.s.s-1\4]&KS-2\11

He adds,the squire on the hypoteneous of a squire collects twice the area of the squire drawn on its side ! B.S.S/1\45,

=:what else they had:=

(i) > the alternate way of converting a circle into a squire [B.S=1/60,AP.S=3/3\ & KA.S=3/14 ]

(ii) & tried to find the value of squire root of2,geometrically ! [B.S=1\61&62,AP.S=1\6]

(iii) He suggested a method for making a squire by adding two different squires ! [ bs=1\50]

(iv) HE even tried to make a squire which was equal to the difference of two squires ! [bs=1\51ap.s=2\15 ]

Apart from these, he gives the referance of six conversions and they are,

A ) How to convert a squire into a rectangle, B ) How to convert a rectangle into a squire! C ) How to convert a squire

in2a rectangle,1of whose side is given! (D)To convert a squire\rectangle in2iso-scalus parall'grm on a given base\line!

(E) To convert a rectangle or a squire in2a triangle ! (F) To convert the squire/ rectangle in2a rhumbus !

[ With gratitude from Ved vigyan shree page no 193-201 ] [ref From B.S=1/52-55, A.S=2/17, 3/1,15/19 & K.S =3/4, 3/12 ]

Some important constructions we get from, Bodhayan Sulva Sutras are :=

(a) How2construct a squire when the side is given ! (B.S=1/29-30,1/42-44&12/28)

(b) How to construct a rectangle on given sides ! [A.S=5/2]

(c) How to construct a parallelogram on a given base line,a side & normal ! [B.S=1/46, A.S=2/2,...
