Download or read book The Hinged Square & Other Puzzles written by Ivan Moscovich and published by Sterling Publishing Company, Inc.. This book was released on 2004 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: A colorful square, dissected into four parts, with hinges marked in black. If you leave the blue piece fixed and swing the others around their hinges, a new shape will emerge. Can you guess just by looking what it will be? This is just one of the tricky geometrical gems that will make a puzzler’s mind work overtime. Try drawing a set of variously shaped polygons using only a compass and a ruler (no measuring allowed!), figuring out which of two sculptures is bigger (logic alone won’t give you the answer), and lots more.
