I think I've got it, and it took me about thirty seconds. I could be wrong of course. I'm not great at this sort of thing. But it does seem obvious. =P
About 15 minutes for me, I think.
But I felt stupid when it clicked for me.
2 minutes...
When I first saw this puzzle years ago, I think I spent about 30 seconds trying to apply Pythagoras, before shouting "Eureka!" ;-)
It took me about 1 second - but then, I do have a mathematics degree
i admit, it took me a little while to get find the solution. i was thinking too hard about it, then felt a little silly after i spotted the simple answer!
I was thinking WAY too hard about it, then read the comments about how easy it was, then immediately saw it.
hahaha... this could have taken a second but I started off thinking and calculating way too hard as well before it finally clicked :) Brilliant!
Tried to work it out the hard way and realized it was WAY simple.
Nice way to make yourself feel smart and stupid at the same time.
5 seconds max! It takes an Architect!
"Well, but isn't it of course....? What am i missing here?" was my thougt.
But then I realized i was right.
(-:
About 20 seconds for the mathematical solution...and then a little smile two minutes later when I saw the elegantly simple visual cue.
