Theorem of Mystery: Part 2
Lopez-Real, Francis
Mathematics Teaching Incorporating Micromath, n209 p5-9 Jul 2008
The Varignon parallelogram has always provided a simple geometric investigation for students that gives rise to a surprising result. It is possible to extend the Varignon investigation by looking at special quadrilaterals or by considering different dissection points along the sides. In the second of his two-part series, the author offers some reflections on and solutions to "The mystery theorem." (Contains 7 figures and 1 note.)
