Inside this Book – This instrument is for measuring and constructing angles. It is shown in Fig. 12. It is used as follows when measuring an angle: Place the lower straight edge on the straight line which forms one of the sides of the angle, with the nick exactly on the point of the angle to be measured. Then the number of degrees contained in the angle may be read from the left, clockwise.
Inside this book –Mechanical Drawing. Elementary and Advanced PDF Book by John S. Reid – This instrument should be held in the same manner as de- scribed for the compass. It is very useful in laying off equal distances on straight lines or circles. To divide a given line into any number of equal parts with the dividers, say 12, it is best to divide the line into three or four parts first, say 4, and then when one of these parts has been subdivided accu- rately into three equal parts, it will be a simple matter to step off these latter divisions on the remaining three-fourths.
