Plane and solid geometry
A secondary-school geometry textbook by Clara Avis Hart and Daniel D. Feldman, published by the American Book Company in New York in 1912 for classroom use. The 316 figures are line diagrams printed on cream stock: lettered polygons, circles with inscribed and circumscribed figures, solid-, dashed- and heavy-weight construction lines, and italic point labels usable as geometric ornament or technical-drawing motifs.
