Hinged dissection

 * ... that the concept of hinged dissections was popularized by Henry Dudeny, who introduced the famous hinged dissection of a square into a triangle (pictured) in his 1907 book The Canterbury Puzzles?

 * Symbol voting keep.svg Length good at 1758, article is new enough, sourcing is good and text is original. Hook is interesting and cited but in a non-free paper book, so I'll AGF on that. Image should be good as it is an original vector based off a 1907 book, and would make a nice, interesting change for the main one. Only thing about the image is that it looks pretty terrible at 100px. As such, I quickly made a square version (ie 2 rows of 2) for DYK, and have replaced the image above. Looks good to go. -Kieran (talk) 06:57, 24 December 2013 (UTC)
