My homepage at http://mysite.mweb.co.za/residents/profmd/homepage4.html has been updated with my 2008 paper on "Generalizing the Nagel line to Circumscribed Polygons by Analogy & Constructive Defining" from the AMESA Journal Pythagoras, the usual bi-monthly mathematical/mathematics education quote, e-Newsletter with info about books, conferences, websites, etc., and a cartoon at the bottom.

My dynamic geometry sketches Link at http://math.kennesaw.edu/~mdevilli/JavaGSPLinks.htm has been updated with "Generalizing the Nagel line to Circumscribed Polygons by Analogy & Constructive Defining", "Nine-point centre & maltitudes of a cyclic quadrilateral", and three new investigations under the link Student Explorations ? "Circle-circumference result", "Triangle Incente-Circumcentre Collinearity" and "Two different centroids (balancing points) of a quadilateral".
