Hanging modified theta graphs are obtained from attaching a modified theta graph to each teeth of comb graph Pa i ⊙ L1, where Pa i denotes a path on ai vertices.In this paper it is proved that symmetric hanging modified theta graphs and non-decreasing symmetric hanging modified theta graphs are graceful.
