Cut the Knot!, Alexander Bogomolny  
Third in a series of columns that draw on Frank Morley's fundamental paper On the Metric Geometry of the Plane nLine. Bogomolny's initial intention was to expose the simplicity of and the motivation behind Morley's original proof of his famous theorem. Then, searching newsgroups archives at the Math Forum, he came across a discussion that began some time in March 1998. After reading a curious remark by one of the participants, he felt that giving additional exposure to Morley's work might be useful... An interactive column for MAA Online that uses a Java applet to simulate a puzzle or mathematical problem, one not stated directly since the applet is intended to be such that the right answer to an as yet unstated problem should be easy to surmise.
