To test each one of these,
square all 3 of the numbers in each choice.

After squaring, if one of them is the sum of the two others, then
congratulations! you found yourself a right triangle :)

still don't get it :/

terenzreignz · Answer

for instance, choice A
$$7, \sqrt{47}, 9$$
Square the lot :)

$$49, 47, 81$$

Look at the biggest, is it the sum of the two smaller ones?
if it isn't, then those are not sides of a right triangle.

Do you get it now? :)
