Welcome to our Geometry class webpage. This is where I'll post in class demos and handy e-files.
Most of our demos will be built with GeoGebra, a very cool, open source tool for creating dynamic mathematical content. You will play with and learn to use GeoGebra this semester.
circs = Table[Circle[{1/(2 n), 0}, 1/(2 n)], {n, 1, 5}];
Graphics[{{Thick, Circle[{0, 0}, 1]},
Table[Rotate[circs, k*Pi/2, {0, 0}], {k, 0, 3}]},
PlotRange -> 2, GridLines -> {Range[-2, 2], Range[-2, 2]}]
