I am trying to square up holes for piers that a soon to be delivered shed will sit on. The four holes need to be spaced at the four corners of 9' x 15'. Using the diagonal measurements, I get 206.5" one way and by moving the last stake I get 206.5" the other way. But the side measurements ended up being 9' on one side and 8' on the other. One foot off. I pulled the 8' corner stake and keeping it on the 206.5 mark, I moved it until it was 9'. But now the one 15' side is 14' 5". If I move the end stake to make it 15', it'll throw that 9' side off. Can't figure it out. Boggles my mind. I look at you tube videos and they say measure your diagonals and if they're the same, it's square! No, it isn't! Tried the 3-4-5 rule and things were wrong there as well. Hope someone can explain what I'm doing wrong. Thanks.
