Summary: A comprehensive treatment is developed of how trigonometry becomes modified when the right angle present in the basic triangle of conventional trigonometry is replaced by some other constant (but arbitrary) angle $\sigma$. The relationship between this generalised trigonometry and the conventional version is explored in some detail.
