Page 259 - The diameter of a circle is a straight line drawn through the center and terminating in the circumference.
Page 375 - Accompanying these are examples for practice which will aid the reader in fixing the principles in mind. In the following pages are given a large number of test questions and problems which afford a valuable means of testing the reader's knowledge of the subjects treated.
Page 264 - 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 168 - May 18th, 1796, provided for the appointment of a surveyor general, and directed the survey of the lands northwest of the Ohio River, and above the mouth of the Kentucky River.
Page 261 - In order to obtain accurate measurements each degree is divided into 60 equal parts called minutes and each minute into 60 equal parts called seconds.
Page 263 - 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 267 - Cycloid. The cycloid is a curve generated by a point on the circumference of a circle which rolls on a straight line tangent to the circle.
Page 273 - With ? 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 114 - To make the line of collimation perpendicular to the horizontal axis of the instrument; and (6) to make the horizontal axis of the telescope perpendicular to the vertical axis of the instrument.
Page 247 - II. To draw the squares for the six figures, proceed as follows : Measure off two inches on either side of the vertical center line and draw light pencil lines through these points parallel to the vertical center line. These lines will form the sides AD and BC of Figs.
