This book is an attempt to present, at an elementary level, an approach to geometry in keeping with the spirit of Euclid, and in keeping with the modern developments in axiomatic mathematics. It is not a comprehensive study of Euclidean geometry-far from it; it is not a survey of various types of geometry. And while it is designed to meet prerequisites in geometry for secondary school teachers, it is neither a review of highschool topics, nor an extension of such topics, as has been customarily covered over the years in books designed for college geometry.
