the pythagorean theorem states that, for a right triangle a^2 + b^2 = c^2

ok...

so, if we want to see whether three numbers make a pythaogrean triple, we plug them into the equation and see if both sides are equal

me no understand

let's take A for example: 7, 24, 25 we can let a = 7, b = 24, and c = 25 7^2 + 24^2 = 25^2 625 = 625 both sides are equal, so this is a pythagorean triple is that clear?

13^2=169 84^2 = 7056 85=7225
Vocaloid
  • Vocaloid
good, now add a^2 + b^2
Vocaloid
  • Vocaloid
169+7056 = 7225, which is equal to c^2, so c is not the answer now try answer choice C

10^2=100 24^2=576 25^2=625

100+576=676 not 625 it could be c
