""The First Two Books of the Elements of Euclid"" is a mathematical treatise written by the ancient Greek mathematician Euclid, and it has been printed chiefly according to the text of Simson in 1852. The book is a compilation of Euclid's geometric principles and proofs, which were groundbreaking in their time and continue to be studied today. The first two books of the Elements deal with the fundamental concepts of geometry, such as points, lines, angles, and circles, and provide proofs for theorems related to these concepts. The text is written in a clear and concise manner, making it accessible to both beginners and experts in the field of mathematics. This edition of the book is based on the text of Robert Simson, a renowned Scottish mathematician who made significant contributions to the study of Euclidean geometry. Overall, ""The First Two Books of the Elements of Euclid"" is a classic work in the field of mathematics and an essential read for anyone interested in the history and development of geometry.With Additional Figures, Notes, Explanations, And Deductions.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
