We construct Lagrange, Hermite and Birkhoff-type operators, which interpolate a given function and some of its derivatives on the border of a triangle with two and three curved edges. We also consider some of their product and boolean sum operators. We study the interpolation properties and the degree of exactness of the constructed operators.
