hexagon fractions

what fraction of the
hexagon is
the orange shape?













this work has been developed and discussed in detail by Derek Ball and Barbara Ball (MT March 2008)

the bottom right-hand picture is a useful starting place
folding bits inwards needs some further justification but is a helpful insight

the top left picture can also use this way of viewing (technique) to help establish the fraction

the other two pictures can be seen as repeated applications of this technique
