First published in 1946, this book was intended to provide students with a sound working knowledge of coordinate geometry. The text contains 'a full discussion of the subject up to conics referred to their axes, using both point equations and parametric methods wherever the latter are suitable'. Exercises and examples are also included.

This small book, translated into English for the first time, has long been a unique place to find classical results from geometry, such as Pythagoras' theorem, the nine-point circle, Morley's triangle, and many other subjects. In addition, this book contains recent, geometric theorems which have been obtained over the past years. There are 27 independent chapters on a wide range of topics in elementary plane Euclidean geometry, at a level just beyond what is usually taught in a good high school or college geometry course. The selection of topics is intelligent, varied, and stimulating, and the author provides many thought-provoking ideas.
