Elementary Synthetic Geometry of the Point, Line and Circle in the Plane by N. F. Dupuis offers a meticulous exploration into the foundations of plane geometry distinct from Euclid's Elements. Published in 1894, this comprehensive guide benefits from Dupuis' extensive teaching experience at the University, translating complex geometric theories into accessible insights. This book provides a robust groundwork in the elements of geometry—points, lines, and circles—while integrating algebraic principles for a thorough understanding. Ideal for both academic use and self-study, this text supports learners in progressing to more advanced studies in Analytical Geometry. Readers will find detailed discussions on congruence, proportion, and the properties of geometric figures, each explained with clarity and precision to ensure mastery of the subject.
