You have 8 wooden right-angle isosceles triangles (the lengths of the two lines that make up the right angle are equal). These are numbered from 1 to 8. Every single triangle is equal in size. Using these triangles how many DIFFERENT squares can you make. (Not neccesarily all at once)
Note: A square must be entirely wooden in order for it count. A square cannot have the exact same combination of triangles that have already been used.e.g if you used triangles 1 and 2 in one combination you can never have a square made from only triangles 1 and 2. (However triangles 1 and 3 would make a distinct square)
(In reply to
re: Solution? by friedlinguini)
No, the problem specifically states that only one square made from each grouping of trianles can count. If you use tiangles 1, 2, 3, and 4 to make square 1234, then squares 1243, 2134, etc do not count, since they use the same grouping of triangles..
