  1. That's intriguing James, and so easy, when you look at the solution!
    Needless to say, I couldn't fathom it out.
    Too much Vino at the weekend, methinks!
    Lovely warm sunny day here, hope it's travelled your way too.

  2. If that were a pure math or geometry problem, I would fail. But it is really only an issue of logic. Once we suspect that the only possible solution is in going inside the triange, it's almost done.

  3. Glad you saw it, Xlbrl. Like Bill, it was too much for me. Trubes - the vini is fine on a day like today.

  4. Obvious when you see it. I did it a different way though. Typical.

    match on top
    match on bottom
    make an x with two matches and lay them on one half so the tops touch at one end and half way along the top and bottom. Repeat for the other side.
