Inspired by the gauge/YBE correspondence this paper derives some star-triangle type relations from dualities in 2d N = (0, 2) U Sp(2N ) supersymmetric quiver gauge theories. To be precise, we study two cases. The first case is the Intriligator-Pouliot duality in 2d N = (0, 2) U Sp(2N ) theories. The description is performed explicitly for N = 1, 2, 3, 4, 5 and also for N = 3k + 2, which generalizes the situation in N = 2, 5. For N = 1 a triangle identity is obtained. For N = 2, 5 it is found that the realization of duality implies slight variations of a star-triangle relation type (STR type). The values N = 3, 4 are associated to a similar version of the asymmetric STR. The second case is a new duality for 2d N = (0, 2) U Sp(2N ) theories with matter in the antisymmetric tensor representation that arises from dimensional reduction of 4d N = 1 U Sp(2N ) Csáki-Skiba-Schmaltz duality. It is shown that this duality is associated to a triangle type identity for any value of N . In all cases Boltzmann weights as well as interaction and normalization factors are completely determined. Finally, our relations are compared with those previously reported in the literature.
