In this video, we discuss important difference between Euclidean, hyperbolic, and elliptic geometry, such as curvature and sums of angles of polygons.

This is part 9 (5/5) 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:
