We can use the above description of the restriction of a line bundle to an orbit to compute the degree of an orbit of dimension one. Let $\Sigma$ be a complete fan and $\tau\in\Sigma^{n-1}$. Hence $V(\tau)$ is a toric curve. Let $\sigma_{1}$ and $\sigma_{2}$ be the two $n$-dimensional cones that have $\tau$ as a common face. Let $\Psi$ be a virtual support function. Choose $v\in\sigma_{1}$ such that $\pi_{\tau}(v)$ is a generator of the lattice $N(\tau)$. Then, by (4.25) and (4.30),
