""A Geometrical Treatment Of Curves, Part 1: Which Are Isogonal Conjugate To A Straight Line With Respect To A Triangle"" is a mathematical book written by I. J. Schwatt and originally published in 1895. The book focuses on the study of curves that are isogonal conjugates to a straight line with respect to a triangle. The author presents a geometrical treatment of these curves, exploring their properties and relationships to other mathematical concepts. The book is intended for advanced students and professionals in the field of mathematics, particularly those interested in geometry and curve theory. It is a valuable resource for anyone seeking a deeper understanding of this area of mathematics.In Two Parts.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
