This one is slightly mored difficult.
But then try the one with the extra 'flap' shown dotted...

Mike Lucey

That was fast Gilles

I can imagine some hair pulling going on in the background with TIG's envelopes

TIG's is not possible if you want the fourth triangle, too. It is for the three of them.

I'm stuck with the extra lap.I'll give it a try later.

I know it's not possible with 4 flaps !
You'll always have a line left over that requires a re-trace!

I was being cruel

Here's the "5 rooms puzzle" The object of the puzzle is to draw a continuous [flat 2d] line that intersects each "wall" of the diagram only once. This example fails as the wall marked with the O is not intersected...

Officially it's "unsolvable"... but there is a tricky solution [that doesn't involve 3d or wormholes!]

Spelling Conondrum.

Move just one matchstick to form a square!

Make four, equilateral triangles of these matches.

I showed you that one when I was in Hungary

Gaieus

Nope. And anyway, how could you remember?

After all, this is a 3D application forum!

(The alignment could be nicer though... )

I should have just burned them.

Here's the solution to the 5-room-puzzle...
It relies on the interpretation that you can intersect a line [wall] at its very end point, thereby allowing you to intersect three at once...

Mike Lucey

Mmmmmm ...... 'end point'
