How can you work out pythagorass theorem?

There are a great number of different proofs of the Pythagorean Theorem. Unfortunately, many of them require diagrams which are hard to reproduce here. Check out the link to Wikipedia's page on the theorem for several different proofs.


Who proved the pythagorean theorem?

Pythagoras, with alternative proofs from lots of others.


Has anyone developed on the Pythagorean theorem after Euclid?

Yes. There are hundreds of proofs of the theorem: some were brought together by ES Loomes in a book called The Pythagorean Proposition.


Did anyone oppose to the pythgreom theorm?

Although the Pythagorean theorem (sums of square of a right angled triangle) is called a theorem it has many mathematical proofs (including the recent proof of Fermats last theorem which tangentially also prooves Pythagorean theorem). In fact Pythagorean theorem is an 'axiom', a kind of 'super law'. It doesn't matter if anyone does oppose it, it is one of the few fundamental truths of the universe.


Is the phythagorean theorem the exact measurement?

Yes, the Pythagorean theorem gives the exact measurements always. It can be backed up by proofs and sin, cosine, etc.


What are some common proofs for the Pythagorean theorem?

the square on the hypoteneuse is equal to the sum of the squares on the other two sides.


What is the proof of the Pythagorean Theorem?

Well, there are many, many proofs of the Pythagorean Theorem. Some sources have as many as 93 proofs. Here is my favorite, but others are listed in the math website in Related Links (below).This is an excerpt from a letter by Dr. Scott Brodie from the Mount Sinai School of Medicine, NY, taken from the first website, proof # 21.The first proof I merely pass on from the excellent discussion in the Project Mathematics series, based on Ptolemy's theorem on quadrilaterals inscribed in a circle: for such quadrilaterals, the sum of the products of the lengths of the opposite sides, taken in pairs equals the product of the lengths of the two diagonals. For the case of a rectangle, this reduces immediately to a² + b² = c².Related LinksA website with 93 proofs of the Pythagorean Theorem. http://www.cut-the-knot.org/pythagoras/index.shtmlAn award-winning applet that demonstrates one of the most famous proofs of the Pythagorean Theorem. http://www.cut-the-knot.org/pythagoras/morey.shtml

Why does the Pythagorean Theorem work in general?

For a number of proofs see: http://www.cut-the-knot.org/pythagoras/ Proof 6 seems to be the most straightforward.


Was the Pythagorean Theorem proven?

Oh yes, the Pythagorean Theorem has been proven.
