Rotations and translations revisited

Bowling Green, April 3 - "Rotations and translations revisited" (contributed talk, 2009 Ohio MAA Spring Meeting). ABSTRACT: "By using a series of elementary plane geometry problems, we will illustrate the general result stating that the composition of a number of plane rotations of angles adding up to an integer multiple of 2*pi is a plane translation. We will discuss the case of collinear rotation centers, the case in which the rotation centers form a regular polygon, a general connection with discrete Fourier transforms, and also a limit case in which the number of rotation centers goes to infinity."
