A DOZEN DISSECTIONS

The traditional Tangram is a dissection of a square based only on

bisections of the sides (plus an effective quadsection). This is one of

the factors that have made it so persistently popular - it is easy to construct, but not always quite so easy to reconstruct.

There are, of course, dozens of such dissections possible, especially if

one allows trisections as well.

Here is just one dozen:

(Note that these diagrams are far too small to be satisfactorily photo- copied - they will just have to be constructed from scratch ... 12 cm equares are convenient.)
