"Write down the mathematical shape names for each of the 7 pieces.
Place the pieces in order of size, with the smallest first.
If a tangram puzzle makes an 8cm by 8cm square, what would be the areas of each of the pieces?
What would be the perimeters of each of the pieces?
What are the angles in each of the pieces?"
Henry Ernest Dudeney, Amusements In Mathematics

"The late Mr. Sam Loyd, of New York, who published a small book of very ingenious designs, possessed the manuscripts of the late Mr. Challenor, who made a long and close study of Tangrams. This gentleman, it is said, records that there were originally seven books of Tangrams, compiled in China two thousand years before the Christian era. These books are so rare that, after forty years' residence in the country, he only succeeded in seeing perfect copies of the first and seventh volumes with fragments of the second. Portions of one of the books, printed in gold leaf upon parchment, were found in Peking by an English soldier and sold for three hundred pounds. A few years ago a little book came into my possession, from the library of the late Lewis Carroll, entitled The Fashionable Chinese Puzzle. It contains three hundred and twenty-three Tangram designs, mostly nondescript geometrical figures, to be constructed from the seven pieces."
