Page 59 - 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 56 - SURFACES. A surface is produced by the motion of a line ; it has two dimensions, — length and breadth. A plane figure is a plane bounded on all sides by lines ; the space included within these lines (if they are straight lines) is called a polggon or a rectilinear figure.

Page 73 - P as a center and any convenient radius (about 2^ inches) draw the indefinite arc ED cutting the line A C. Now with the same radius and with D as a center, draw an arc P Q. Set...

Page 63 - A cone is a solid bounded by a conical surface and a plane which cuts the conical surface. The plane is called the base and the curved surface the lateral area.

Page 64 - A sphere is a solid bounded by a curved surface, every point of which is equally distant from a point within called the center.

Page 63 - A right cylinder or a cylinder of revolution is a cylinder generated by the revolution of a rectangle about one side as an axis.

Page 59 - The diameter of a circle is a straight line drawn through the center and terminating in the circumference. A radius is a straight line joining the center with the circumference. It has a length equal to one half the diameter. All radii (plural of radius) are equal and all diameters are equal since a diameter equals two radii. PENTAGON.

Page 92 - R' with the arc drawn through the point H is a point upon the curve. Also the arc whose center is S' with the arc drawn through the point I is another point on the curve. The remaining points are found by repeating this process. PROBLEM 27. To draw an Hypocycloid when the diameter of the generating circle and the radius of the director circle are given.

Page 118 - B, let the vertex of the cone be placed at V, and one element of the cone coincide with VA I. The length of this element is taken from the elevation A, of either contour element. All of the elements of the cone are of the same length, so when the cone is rolled each point of the base as it touches the plane will be at the same distance from the vertex. From this it follows that the development of the base will be the arc of a circle of radius equal to the length of an element. To find the length...

Page 129 - H with two faces parallel to V; the diagonal from the front upper right-hand corner to the back lower left-hand corner is indicated by the dotted line. Swing the cube around until the diagonal is parallel with V as shown in the second position. Here the front face is at the right. In the third position the lower end of the diagonal has been raised so that it is parallel to H, becoming thus parallel to both planes. The plan is found by the principles of projection, from the elevation and the preceding...
