Some Interesting and Thought-Provoking Geometric Fallacies
Sultan, Alan
Mathematics Teacher, v101 n2 p114-119 Sep 2007
In this article, the author presents some interesting geometric fallacies that were used in a problem-solving course for preservice high school mathematics teachers. He states that presenting these fallacies in ordinary math classes can enrich the class by making the students think hard about both the theorems themselves and the steps in the proof of the theorems. These kind of fallacies engage students, get them involved in the discovery process, and helps them see that mathematics can be fun. (Contains 6 figures.)
