Aug 8, 2012 at 18:23 comment added Andrew D. King Let the distance between $x$ and $y$ be the square of the sum of the weights on the path between them. Then, as you can see with a path on three vertices where both edges have weight 1, the triangle inequality does not hold. Think of any semi-metric you can form on a subset of $\mathbb R^1$. Then you can form that on an edge-weighted path.
