Page 32 - A sector, is any part of a circle bounded by an arc, and two radii, drawn to its extremities. A quadrant, or quarter of a circle, is a sector having a quarter part of the circumference for its arc, and the two radii perpendicular to each other.

Page 155 - However, a similar effect can be easily produced by a few shading lines, i which are or should be drawn in accordance with the rules followed in shading proper. To commence with a simple example, that very often in many forms appears on machine drawings, we have in Fig. 19 a' vertical hexagonal prism, with its front face in the light or illuminated. Such surfaces parallel to the vertical plane would receive flat tints, and the nearer the surface is to the eye the lighter such tints would be, and...
