Question

Which of the following sets of numbers is a Pythagorean triple?
a.4, 5, 6
b.8, 15, 17
c.5, 12, 14
d.8, 24, 25

Answer 1

Use the Pythagorean theorem : a^2 + b^2 = c^2

Answer 2

Plug each option in, in order of the choices. Whenever you have questions like these, the choices are practically written as a, b, c, so it is simple to plug in, and you will reach the answer once you notice both sides of the equation are equal to each other.

Answer 3

But it has no triangle.

Answer 4

I know, there may not be a triangle. But that's why it's referring to "Pythagorean triple" instead of "right triangle".

Answer 5

That makes sense.
