METHOD OF COPYING BY TRIANGULATION
To enlarge or reduce one may resort to any of the following methods:
(i) Photography.
(2) The mechanical instrument known as the pantograph.
(3) The mechanical instrument known as the proportional dividers.
(4) Free hand drawing. Good practice, but not conducive to accuracy.
(5) Squaring the original by means of intersecting horizontal and vertical lines. This requires great care in preparation and use. The squares must be square and usually require numbering along at least two sides of the original and of the copy.
(6) Triangulation. An old and simply made geometrical form which I have adopted for the purpose of enlarging and reducing.
In my practice it has, since my discovery of its new use, entirely superseded the laborious, if time-honored, methods. By its use ordinary care produces accurate work, no measurements being required except when laying out the perimeters.
