## Pythagoras Theorem: x2+y2 = z2. But Why ?

The Pythagoras theorem is named after the Greek mathematician Pythagoras. It is considered as one of the first mathematical proofs. This theorem is proved in many different ways and here I am with one of the proofs solved through geometry.

### Why (a+b) 2 = a2+b2+2ab ?

Not everybody knows why a plus b whole square is i.e. (a+b) 2 = a2+b2+2ab and why exactly it has been generalized.So, here I come up with the geometrical proof that shows up the results.
