Hi everybody, a new diagram of a puzzle designed by me was just published on The Fold, the Trapezium puzzle, https://origamiusa.org/thefold/article/diagrams-trapezium-puzzle. I like it because it follow the rule: fold-play-study. In fact the diagram shows a very simple way to FOLD an isosceles trapezium. With four pieces you can PLAY solving the puzzles. And because in the sequence you have the trisection of a right angle, then you have an equilateral triangle and, of course, the trapezium itself, you can use it to STUDY geometry. I like the fact that this model can be used for teaching purposes that's why I decided to make it available for all. So fold it, teach it, share it but don't make money out of it, or at least give me my cut :-) Hope you like it and I will be happy to know if you will use it in your classroom. Happy folding Francesco
