_Geometrical Puzzle_ shown in Fig. 56. Each of these consists of a
capital letter divided up by one or two straight lines into right-angled
triangles and other geometrical shapes. While very simple to look at
when completed, these little puzzles are by no means easy to solve when
the odd pieces are given in a jumbled state. The capital letters should
be drawn on a piece of cigar-box wood, and then carefully cut out with a
fret saw, or, better still, with a tenon saw if you have one. If you
cannot manage wood, then the puzzle can be done in stout cardboard and
cut out with a sharp thin knife.
