A Course of Pure Geometry: Properties of the Conic Sections
by E.H. Askwith
Publisher: Cambridge University Press 1917
Number of pages: 314
The book does not assume any previous knowledge of the Conic Sections, which are here treated ab initio, on the basis of the definition of them as the curves of projection of a circle. Many of the properties of the Conic Sections which can only be established with great labour from their focus and directrix property are proved quite simply when the curves are derived directly from the circle.

by G. A. Wentworth - Ginn & Company
Introduction to geometry, the straight line, circle, proportional lines and similar polygons, areas of polygons, regular polygons and circles. The book includes exercises: theorems, problems of construction, loci, and problems of computation.
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.
