Foundations in Geometry
Revised: August 2007
Axiomatic approach to the study and development of Euclidean and non-Euclidean geometry.
Prerequisite: Junior standing or permission of Department Head.
At the conclusion of this course, the successful student will demonstrate
1. knowledge of the synthetic, investigative, and deductive approaches to Euclidean
2. knowledge of the historical and mathematical significance of the parallel postulate,
including an introduction to a non-Euclidean geometry.
3. proficiency in the basic concepts of mathematical logic and their use in proofs.
