Nuprl Lemma : geo-same-side_wf
∀[e:BasicGeometry]. ∀[A,B,P,Q:Point]. (P,Q-AB ∈ ℙ)
Proof
Definitions occuring in Statement :
geo-same-side: A,B-PQ,
basic-geometry: BasicGeometry,
geo-point: Point,
uall: ∀[x:A]. B[x],
prop: ℙ,
member: t ∈ T
Definitions unfolded in proof :
uimplies: b supposing a,
guard: {T},
so_apply: x[s],
basic-geometry: BasicGeometry,
prop: ℙ,
implies: P ⇒ Q,
so_lambda: λ2x.t[x],
subtype_rel: A ⊆r B,
geo-same-side: A,B-PQ,
member: t ∈ T,
