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
Now use the 6 pieces to make
A Square A Rectangle A Parallelogram
An Isosceles Trapezium A Right angled Triangle
Now use all 6 pieces to make these shapes
