My Dynamic Geometry Sketches at
http://math.kennesaw.edu/~mdevilli/JavaGSPLinks.htmhave been updated with:
"A Generalization of Neuberg's Theorem and the
Simson line",
and some new Student Explorations like:
"Area ratios of inscribed polygons"
and a really cool "Finding the median and centroid of a
triangle by experimentation: A gravity simulation."
A link for doing "Turtle Geometry" online has also
been added at the bottom of the first page.
