CategoryTheory.Bicategory.Adjunction.right_triangle

∀ {B : Type u₁} [inst : CategoryTheory.Bicategory B] {a b : B} {f : a ⟶ b} {g : b ⟶ a}
  (self : CategoryTheory.Bicategory.Adjunction f g),
  CategoryTheory.Bicategory.rightZigzag self.unit self.counit =
    CategoryTheory.CategoryStruct.comp (CategoryTheory.Bicategory.rightUnitor g).hom
      (CategoryTheory.Bicategory.leftUnitor g).inv

The composition of the unit and the counit is equal to the identity up to unitors.
