@article{Beauregard2006NoAC, title={No Arithmetic Cyclic Quadrilaterals}, author={Raymond A. Beauregard}, journal={The College Mathematics Journal}, year={2006}, volume={37}, pages={110 - 113} }

Ray Beauregard (beau@math.uri.edu) received his B.A. from Providence College in 1964 and his Ph.D. in 1968 (under the guidance of Richard E. Johnson) from the University of New Hampshire. He has spent his entire career at the University of Rhode Island (Kingston, Rl 02881). He and John Fraleigh are the co-authors of a textbook, Linear Algebra, currently in its third edition. Although most of his research has been in ring theory, he has recently become interested in elementary number theory. His…
