They would be if it turns out that c² = a² + b² is true.
c² = a² + b²
8² = 7² + 5²
Let's find out if that's true. 8²=64, 7²=49, 5²=25
64 = 49 + 25
1
49
+25
74
No, because we had to carry that 1 when we added, and
that made it come out 74 istead of 64. If only we
hadn't had to carry that 1 they would have been the
measurements of the sides of a right triangle. But
since we had to carry that 1, they aren't. Too bad.
