Type-2 fuzzy sets are fuzzy sets whose membership values are fuzzy sets on the interval (0, 1). This concept was proposed by Zadeh, as an extension of fuzzy sets. Type-2 fuzzy sets possess a great expressive power and are conceptually quite appealing. Also fuzzy matrices play an important role in scientific developments. In this paper, adjoint of type-2 triangular fuzzy matrices (T2TFM) is proposed. Some more special properties of adjoint of T2TFM which are useful for finding inverse of T2TFM are presented. Numerical example is also included.
