Disputed answer in basic geometry mastery

Hvordan kan vi hjælpe?

There was a question in the mastery section (which I unfortunately went passed before thinking I should report the issue). It was a Pythagorean Theorum question and it was a multi choice answer (choose all that apply). It asked which side lengths make up a right angled triangle and one of the possible answers was : 2, 3, square root of 5. (Not sure how to do the symbols on iPad).

Now I said yes this one does, but the offical answer was no it doesn't. Can we confirm and clarify this?

My working: 2^2 + (square root of 5)^2 = 3^3

4+5=9

Sarah Watkeys,

Your math is correct, unless the order of the numbers listed mattered for the question.

If the order matters then 2^2 + 3^2 does not equal (sqrt5)^2.

It would be helpful if you had a screenshot of the question you believe is incorrect.

If you come across another mistake in a question you can use the report a problem button in the bottom right corner. It should look like this:

Unfortunately I went past the question before I thought to do so. Definitely didn't say order mattered. Thanks for that though, I was beginning to doubt myself
