### MAT 360  Geometric Structures   Spring 2012  Tue & Thu 2:20 - 3:40 p.m. S B Union 231

Instructor: Ljudmila Kamenova

e-mail: kamenova@math.sunysb.edu.
Office: Math Tower 3-115
Office hours: Wednesday 4-6 p.m. in 3-115 and Wednesday 1:30 - 2:30 p.m. in the MLC

This is a course in planar geometry, covering both Euclidean and non-Euclidean geometries. It is assumed that you have already had a high-school course in Euclidean geometry (more precisely, know the geometry covered in MAT 200). Our approach will be primarily axiomatic. We will be doing a lot of proofs, so it is crucial that you be familar with basic logic and proof techniques (again, as covered in MAT 200).

Required text: Euclidean and Non-Euclidean Geometries , by Greenberg, 4th edition, Freeman, W. H. & Company

Other texts: Kiselev's Geometry, Book I. Planimetry , adapted from Russian by Alexander Givental, Sumizdat, El Cerrito, Calif., 2006.
