Abstract.   In this paper we present some spherical f-tilings by two (distinct) right triangles. We classify the group of symmetries of the presented tilings and the transitivity classes of isohedrality are also determined.

Keywords:  dihedral f-tilings; spherical trigonometry; combinatorial properties; symmetry groups.
