We define a fourth basic invariant, which, besides the lengths of the three sides of a triangle, determines a triangle in the complex and quaternion projective spaces CP" and HP" (n ~> 2) uniquely up to isometry. We give inequalities describing the exact range of the four basic invariants. We expres
