Nuprl Lemma : geo-X_wf
∀e:EuclideanPlaneStructure. (X ∈ Point)
Proof
Definitions occuring in Statement :
geo-X: X,
euclidean-plane-structure: EuclideanPlaneStructure,
geo-point: Point,
all: ∀x:A. B[x],
member: t ∈ T
Definitions unfolded in proof :
pi2: snd(t),
implies: P ⇒ Q,
prop: ℙ,
exists: ∃x:A. B[x],
sq_exists: ∃x:{A| B[x]},
so_apply: x[s],
so_lambda: λ2x.t[x],
subtype_rel: A ⊆r B,
uall: ∀[x:A]. B[x],
geo-X: X,
member: t ∈ T,
all: ∀x:A. B[x]
