Re: [ASK] G to BH

hi Monox D. I-Fly

I assumed that E is 'above' A, F 'above' B and so on.  And then didn't get your answer.

So I tried E 'above' D, F 'above' C and so on.  And got a different answer to us both.

So it would seem that the exact diagram is important here.

Re: [ASK] G to BH

Your first assumption was right. What answer did you get?

Re: [ASK] G to BH

With that arrangement of the letters, BH is a diagonal and AG another.  The diagonals cross at 90 degrees and bisect each other, so the distance required is half a diagonal.
