Question

Which set of numbers represents a Pythagorean triple?
a; 6, 9, 12
b; 7, 10, 12
c; 16, 18, 25
d; 27, 36, 45

Answer 1

can someone explain to me how to do this?

Answer 2

A Pythagorean Triple is a set of 3 numbers that can represent the three sides of a RIGHT triangle.

For example, 3,4,5 can represent the sides of a right triangle becuase 3^2 + 4^2 = 5^2
9 + 16 = 25

SO go through the choices and determine which set of numbers will a^2 + b^2 = c^2.
