| Title: | Grade School Triangles and Ailles' Rectangle |
| Speaker: | Jack Calcut Assistant Professor Department of Mathematics Oberlin College Oberlin, Ohio |
| Abstract: | In grade school, students learn a standard set of Euclidean triangles. Among this set, the usual 45-45-90 and 30-60-90 triangles are the only right triangles with rational angles and side lengths each containing at most one square root. Are there any other such right triangles? We answer this question and present an elegant complement, called Ailles' rectangle, that deserves to be in every geometry teacher's toolkit. |
