Page 3 - vessel" includes every description of water craft or other artificial contrivance used, or capable of being used, as a means of transportation on water.
Page 8 - A Circle is a plane figure bounded by a curved line every point of which is equally distant from a point within called the center.
Page 12 - A pyramid (Fig. 54) is a solid whose base is a polygon and whose sides are triangles uniting at a common point, called the vertex.
Page 6 - A polygon is a plane figure bounded by straight lines. The term is usually applied to a figure having more than four sides. The bounding lines are called the sides, and the sum of the lengths of all the sides is called the perimeter of the polygon. 63. A regular polygon is one in which all the sides and all the angles are equal. 64. A polygon of five sides is called a pentagon ; one of six sides, a hexagon ; one of seven sides, a heptagon, Pentagon. Hexagon. Heptagon. Octagon. Decagon. Dodecagon.

Page 131 - GH indicates that only a part of the rivet is shown. This is done so as not to take up too much space on the drawing. Fig. 9 shows an...
Page 103 - The circumference of a circle is equal to the diameter multiplied by 3.1416.
Page 67 - AC should be, for this plate, 1^" long. Produce AC to B. From C as center, with a radius equal to CA, describe the semicircle A 128456 7 B, and divide it into as many equal parts as there are sides in the required polygon (in this case eight). From the point C, and through the second division from B, as 6, draw the straight line C6.
