You can put this solution on YOUR website! A 6,8 and 10
B 2,3 and 4
C 5,12 and 13
D 8,15 and 17
Try them all in the Pythagorean theorem and see
which ones, if any, check correct and which ones,
if any, don't check:
6² + 8² = 10²
36 + 64 = 100
100 = 100
That checks.
2² + 3² = 4²
4 + 9 = 16
13 = 16
That doesn't check.
5² + 12² = 13²
25 + 144 = 169
169 = 169
That checks.
8² + 15² = 17²
64 + 225 = 289
289 = 289
So the only one that doesn't check is
B 2,3 and 4
