Will do. Thanks

[Tilly2]

Thank you. Maybe I will get it if you explain it to me.

If you drew the net of the cube (or unfolded the cube into a 2d cross shape) then the two angles (at 45 degrees each) would total 90 degrees.
But in 3d the angle is 60 degrees as you can add a third diagonal on the hidden left hand face to form an equilateral triangle

ThQ2 is one of those where you have to ask one of the aliens "if I asked the other alien which way to go what would he say?"

[Tilly2]

That's it! I get it now. You are a little treasure! Thank you. That's been bugging me all day.

[Tilly2]

It has to be a yes/no answer though. So that doesn't work.

[factor-fiction]

Ok- so you point in one of the two directions and ask something like "if I asked the other alien whether this was the right way would he say 'yes'"

That's very clever, to me at least. NNN.
