Equidecomposability of a Regular Triangle and A Square of Equal Areas

摘要

This paper deals with the subject of the first chapter of the second author's book Mathematical Time Exposures: The equidecomposability of a regular triangle and a square of equal areas. A new solution of the problem is given, which also shows that the solution of the problem as given in the third edition of Hogo Steinhaus 'Mathematical Snapshots', is not correct. (Author)
