Please check this out first: http://www.milaadesign.com/triangle.html The triangle area is 32.5 square cm however the individual items only account to 32 sq cm. Initialy the image forms a perfect triangle with same proportions however when rearanged the area in black around 0.5 sq cm becomes obvious yet all the pices fit into the area of the triangle. What happens?

I'm glad to have been able to help you with this. It's an interesting problem, and one that has been around (in various forms) for a very long time. I remember having encountered a similar problem in the 1960s. I believe it may have been in Martin Gardner's column in "Scientific American." Online, the problem is sometimes called "Simeon's Triangle." For the record, here's an explanation: The Mysterious Square Problem http://www.scientificpsychic.com/mind/triangle1.html This is the search strategy I used to find the link above. In case you're interested in additional material, this Google search string will take you to several sites which explain the problem: Google Web Search: triangle "32.5 square" ://www.google.com/search?hl=en&q=triangle+%2232.5+square%22 Very best regards, pinkfreud

Yup - it's simply the fact that there IS NO 13x5 triangle. There is a 2x5 and a 3x8, but they are NOT similar triangles, and they do NOT fit together to make a 13x5. Wow, that one stumped me too.
