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 and cartoon at the bottom.

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".
