If i measure a hypotenuse and i get 11 and then i double check my work by doing the a squared + b squared = c squared method and i get 12 why would these two be different

Hi there!

Sometimes, like you said, you might don't get the exact answer when you justified your answer. In this case, you need to take the nearest number. So if you got 11 then 12 is the nearest number, just go for it.

Or go back and start over and see if you didn't miss anything.

I hope this helps!
