Tangram - 6
pieces
Here is how to make a 6 piece
Tangram from the standard matchbox.
First squash the matchbox
flat. It should make a square. 
Then draw the two diagonals
of the square.
Cut out the Triangle ABC.
This should open to give a
square.
The two pieces you have made
should now open out to look like this;

Draw the lines DF and EF
using the existing creases to guide you. Cut along DF and EG.
Also cut the square piece in
half along JK.
Now you have 6 pieces;
4 equal triangles and two
“chevrons”, a small one and a large one:

These will be the 6 pieces
that make up your Tangram
