We will prove the relations between the Dg-orthogonality and the g-orthogonality. Moreover, we study the Dg-angle and its properties in normed spaces. We also prove the relations between the g-angle and the Dg-angle. ## Keywords - Orthogonality - Mathematics - Pure mathematics - Physics - Mathematical analysis - Geometry --- Sumber: Discover Unhas — RIMS Universitas Hasanuddin.
