A School Geometry Part-I-VI, 1/Ed.

In the present edition some further steps have been taken towards the curtailment of bookwork by reducing certain les important propositions (e.g., Euclid I. 22, 43, 44) to the rank of exercises. Room has thus been found for more numerical and graphical exercises, and experimental work such as that leading to the Theorem of Pythagoras.

Theorem 22 (page 62), in the shape recommended in the Cambridge Schedule, replaces the equivalent proposition given as Additional Theorem A (page 60) in previous editions.

In the case of a few problems (e.g., Problems 23, 28, 29) it has been thought more instructive to justify the construction by a preliminary analysis than by the usual formal proof.
