Nuprl Lemma : geo-proper-segment_wf
∀[e:EuclideanPlaneStructure]. (geo-proper-segment(e) ∈ Type)
Proof
Definitions occuring in Statement :
geo-proper-segment: geo-proper-segment(e),
euclidean-plane-structure: EuclideanPlaneStructure,
uall: ∀[x:A]. B[x],
member: t ∈ T,
universe: Type
Definitions unfolded in proof :
prop: ℙ,
geo-proper-segment: geo-proper-segment(e),
member: t ∈ T,
uall: ∀[x:A]. B[x]
