Prisms may be either right or oblique. The convex surface of a right prism consists of rectangles. Fig. 1 is a right prism; Fig. 2 is an oblique prism. NOTE. — When a prism is spoken of, a right prism is meant unless the word oblique is used. The altitude... Higher Arithmetic - Page 791by John Henry Walsh - 1893Full view - About this book
