Question 2
Some
time ago we were introduced to the world's simplest, yet very pleasing,
wooden puzzle. It consists of just two pieces of wood and when you place
them together correctly you just know that you have solved the puzzle.
Here is a variation on the puzzle which has four pieces
all the same shape that are made by cutting out and gluing the nets on the
linked page.
Net
for Puzzle Pieces
Challenge
To arrange the four 3D puzzle pieces to make a tetrahedron.
To make the puzzle pieces, you need:
copies of the net made on card (2 sheets)
scissors
ruler
quick-drying glue.
There is a neat method of making the folds easily. Hold
a ruler along the lines of the net and, with a point of your scissors,
lightly run down the line to score the card. This will make it easy to
fold.
Please send a photo of your completed pieces as well as a photo of the
pieces arranged to make tetrahedron.
