Here for the first time, we propose a new method of constructing two different modal operators, using a compass-andstraightedge construction, producing for each point from the intuitionistic fuzzy interpretational triangle, the two points onto the triangle’s hypothenuse that are respectively equidistant from the Truth and the Falsity as the point itself. The properties of these so-constructed new intuitionistic fuzzy operators are studied and formulated in two theorems.
