The requirement that the low-energy theorems of broken chiral symmetry be compatible with calculations based on effective vertices and vector-meson dominance leads to a number of relations among strong interaction quantities. Here we use this approach to determine the ω→3π contact term, and comment on a number of recent investigations along these lines.
