In this video, we present a finite geometry, which we dub 4-point geometry, which will turn out to be the order 2 affine geometry.
This is part 3 (3/3) of the lecture series offered by Dr. Andrew Misseldine for the course Math 3130 - Modern Geometries at Southern Utah University. A transcript of this lecture can be found at Dr. Misseldine's website or through his Google Drive at:
