Question

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

18, 24, 42
45, 28, 53
15, 30, 45
33, 77, 22

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
