This machine was used to simplify calculations involving triangles, using a mathematical
technique known as trigonometry. Surveyors rely extensively on this practice as it enables
huge areas to be surveyed using the lengths and angles of triangles.
The operator used the machine by ‘drawing’ the problem on it. It contained three rules
which could be moved using dials to make a triangle of the required size. Angles or lengths
could then be read off directly. However, it was expensive and did not catch on.
