```
Um, Pythagorean Theorem, rather.
```

I am tempted to say that you are right, but my pedantic nature

compels me to provide explanation why I attributed method to

Archimedes.

Pythagoras was a geometer and his theorem was about equality of

areas formed by a square where hypotenuse was a side and two square

formed by catheti in the same manner. However, Pythagoras did not go

further than that in his thinking. Euclid, Heron of Alexandria,

Archimedes, and others were looking to expand usefulness of knowledge

of triangles. Nowadays, application of triangles involve use of

Trigonometry, which requires use of irrational functions. Ancient

greeks could not compute them and even if they could, it was too

labor intensive. So methods using quadrances ( squared distances )

and spreads ( squared sines of angles ) were developed. Archimedes

deserves a lot of credit for his insights into Pythagorean theorem

and it’s application. Also the theorem itself does not belong to

Pythagoras. It’s knowledge predates Greeks and could be traced to

Babylonian civilization. Pythagoras was the first who developed

proof of the theorem. So one would not be wrong in referring to

method as Pythagorean. On the other hand, could we credit the guy,

who invented the wheel, with invention of automobile?
