I have to do a trifold board about tangrams for math fair, and I was wondering if anyone had any resources or information to give me. I am looking along the lines of these questions. 1. What is the known history of tangrams? 2. What are the mathematical requirements for tangrams? 3. What kinds of shapes can be made with the seven tans?
