Borcbardt and Perrott:Geometry for Schools

Abstract

This is a useful volume covering the ground of the first two books of Euclid. The strictly deductive proofs of the more fundamental propositions are given in 26 Theorems and 13 Constructions of stage III. But the substance of almost all the remaining propositions with their ordinary modern extensions is given in the supplementary Theorems A-X; and a few important Problems, including Euo. II, 11 and 14, are discussed as Addenda.
