Euclidean & Non-Euclidean Geometry

In the Spring of 2011 I took Dr. Manizade's Euclidean & Non-Euclidean Geometry course through Radford University.  Because I am a Geometry teacher, this class was immensely helpful to me in my teaching.  We did lots of easy activities to show concepts to students, like how to show the formula for area of a circle.  I also enjoyed doing the basics of spherical geometry, like great circles = lines.  I also liked some of the teaching ideas and strategies I received, like keeping a journal, that I plan to incorporate into my own classroom.
