摘要：
We prove that every triangle-free planar graph is the graph of intersection of a. set of segments in the plane. Moreover, the segments can Le chosen in only three directions (horizontal, vertical and oblique) and in such a way that no two segments cross, i.e., intersect. in a common interior point.
