چکیده

In this paper‎, ‎we introduce some new concepts of fuzzy graphs with the notion of degree of an edge in fuzzy line graphs and congraphs‎. ‎Also‎, ‎some properties and some‎ ‎lemmas of edge fuzzy line graphs and congraphs are studied‎. ‎Finally‎, ‎we state and prove some results‎ ‎related to these concepts.
