Abstract: Let be the interior of a compact 3-manifold with boundary, and let $\mathcal{T}$ be an ideal triangulation of This paper describes necessary and sufficient conditions for the existence of angle structures, semi-angle structures and generalised angle structures on $(M; \mathcal{T})$ respectively in terms of a generalised Euler characteristic function on the solution space of the normal surface theory of $(M; \mathcal{T}).$ This extends previous work of Kang and Rubinstein, and is itself generalised to a more general setting for 3-dimensional pseudo-manifolds.
