Question

Which of the following sets of numbers is not a Pythagorean triplet?

12, 16, 20

14, 48, 50

16, 30, 34

20, 48, 56

Answer 1

You can check each by simply plugging the values into the pythagorean theorem : a^2+b^2=c^2

In this case, the last set of numbers is not the pythagorean triplet. It comes out to 20^2+48^2=?= 6^2
2704=/=3136 which is not true

Answer 2
