Question

The following sets of numbers are possible side lengths of a triangle. Which of the following sets forms a Pythagorean triple?

Answer 1

I would say C as the answer

Answer 2

The first choice is not a triangle  because 42 = 18 + 24 You cant draw a tangle with these measurements  = In fact they make  a straight line.

The  same goes for choice 3 (45 = 30 + 15)

The second one forms a Pythagorean Triple  53^2 = 28^2 + 45^2

The last one does nt form a triangle  because  77 > 22 + 33
