what are the proofs of pythagoras theroem?

Answer 1

There are 69 proofs listed at the link below. They actually go through them.

Answer 2

WEll there is something called the Pythagorean trio. If the rule is 'a'('a') + 'b'('b') = 'c'('c'). Then that means 'a' plus 'b'/2 must equal 'c'. What this means is if the numbers are 3, 4 and 5. 3 plus 2 should be 5. 3 plus 2 because half of four is 2. You can also try this with 6, 8, and 10. 6 plus four equals 10, etc.

Answer 3

Answer 5

A red Indian was walking along past some wigwams. He saw his mates wife sitting outside her wigwam, she was sitting on a Hippopotamus hide. He fell in love with her.
He asked his mate if he could spend the night with her, in return for a night with his wife.
His mate said "I'm interested, but let me see your wife."
So they went off to see the first Indian's wife. His wife was sitting on a coyote hide, his mate said "she's not bad, but my wife is pretty stunning, sorry no deal."
The first Indian was really desperate, so offered his other mates wife, who he was having an affair with. They went to look at her, she was sitting on a buffalo hide.
His mate said "look I'll go for it if I can have both" The first Indian immediately agreed.
Thus - The squaw on the hippopotamus is equal to the sum of the squaws on the other two hides.
QED
If you are not convinced you could draw a right angled triangle, and draw a square on each side. Measure the squares on each side.

Answer 6

a2 + b2 = c2 , where c is the hypothenuse (longest side of the triangle)... this only applies to right triangles (containing a 90 degree angle), the other proof is that the sum of the two angles which are not the right triangle will equal 90 degrees
