Theorem diass 37117

Description: The value of the partial isomorphism A is a set of translations i.e. a set of vectors. (Contributed by NM, 26-Nov-2013.)

Hypotheses

Ref	Expression
diass.b	⊢ 𝐵 = (Base‘𝐾)
diass.l	⊢ ≤ = (le‘𝐾)
diass.h	⊢ 𝐻 = (LHyp‘𝐾)
diass.t	⊢ 𝑇 = ((LTrn‘𝐾)‘𝑊)
diass.i	⊢ 𝐼 = ((DIsoA‘𝐾)‘𝑊)

Assertion

Ref	Expression
diass	⊢ (((𝐾 ∈ 𝑉 ∧ 𝑊 ∈ 𝐻) ∧ (𝑋 ∈ 𝐵 ∧ 𝑋 ≤ 𝑊)) → (𝐼‘𝑋) ⊆ 𝑇)

Proof of Theorem diass

Dummy variable 𝑓 is distinct from all other variables.
