Timber framers are familiar with geometric methods of
determining angles in a complex roof. Trigonometry has a place in programming worksheets
and calculators for quick solutions to any desired degree of accuracy.
Although somewhat more abstract than the above two mathematical tools, the vectors and
matrices of linear algebra will also solve angles. Applied properly,
these techniques will solve problems which deviate from the Pitch / Pitch / Deck Angle
norm, and are often otherwise intractable.
