The subject-matter of these pages is virtually that of the first three books of the Elements, but there is a great departure as regards the order and the method. As the pupil proceeds with his experiments and observations he is helped to build up ideas about lines, points, triangles, circles, etc., in precisely the same way as that followed in dealing with the elements of physics and chemistry.

This book is intended for use by a parent and a child. It is recommended that the parent have some familiarity with geometry, but this is not necessary. The parent can simply read the chapter before teaching the child and then learn it together.

For a generation this was the leading textbook on the subject of plane geometry in America. Topics covered: rectilinear figures, the circle, proportion, similar polygons, areas of polygons, regular polygons and circles, etc.
This geometry text is written for the Pre-university students to serve as an introduction to Higher Elementary Geometry, either as a subsidiary or a main Subject. The aim is to give to the Students certain Elementary ideas about the subject.

This text is intended for a brief introductory course in plane geometry. It covers the topics from elementary geometry that are most likely to be required for more advanced mathematics courses. The only prerequisite is a semester of algebra.
