SA>Martin Gardner gave the 9 triangle dissection in "The Last Recreations" p253 (but Google books and Amazon wont show me that page) Stuart Anderson
[...] This is mysterious. Neil just sent me some screenshots of his electronic edition. P253 is a pure text description of a map-coloring game. Triangular dissections are discussed on pp250 and 252, with illustrations of three dissected squares filling p251, and no mention in the text of nonasecting the 45-45-90 into acute isosceles. Is it likely Neil's edition isn't the latest? --rwg
Nothing mysterious, I assumed (and made an ass of u and me) the diagrams discussed in the text were all given in illustrations in the following pages, but looks like he didnt give the 9 triangle dissection.
