Toric Variety

Let $m_1$, $m_2$, ..., $m_n$ be distinct primitive elements of a 2-D Lattice $M$ such that ${\rm det}(m_i,m_{i+1})>0$ for $i=1$, ..., $n-1$. Each collection $\Gamma=\{m_1, m_2, \ldots, m_n\}$ then forms a set of rays of a unique complete fan in $M$, and therefore determines a 2-D toric variety $X_\Gamma$.
