1it can be proved by the results of similarity in a right triangle by dropping an altitude from a vertex and writing the ratio of sides to be equal ............
done it many times b4 ya its interesting though
62The most wonderful proff is to inscirbe a square iinside another
take the length of the larger side be a + b
and the smaller be c
now area is sum of areae of the right angled triangles and the smaller square...
try using this hint or i will post the solution once i am back home :)

This image is from wikipedia...
area of the largest square is
(a+b)2 = 1/2ab. 4 + c2
hence a2+b2=c2
33These all proofs is now in CBSE also in maths practical now a days [1]
