Respuesta :
He is wrong because if a + b > c it doesn't follow that a^2 + b^2 > c^2
(a + b^2 will always be greater than c^2 but a^2 + b^2 will not always be.
.
An example:
Right angled triangle with sides 3, 4 and 5:-
3 + 4 > 5 but 3^2 + 4^2 = 5^2
(a + b^2 will always be greater than c^2 but a^2 + b^2 will not always be.
