By generalizing the idea of extended triangle of a graph, we succeed in obtaining a common framework for the result of Roberts and Spencer about clique graphs and the one of SzwarcΓΏter about Helly graphs. We characterize Helly and 3-Helly planar graphs using extended triangles. We prove that if a pl
