Nuprl Lemma : geo-between-outer-trans2

∀e:BasicGeometry-. ∀[a,b,c,d:Point].  (B(abd)) supposing (B(bcd) and B(abc) and b # c)


Proof




Definitions occuring in Statement :  basic-geometry-: BasicGeometry-,  geo-between: B(abc),  geo-sep: a # b,  geo-point: Point,  uimplies: b supposing a,  uall: ∀[x:A]. B[x],  all: ∀x:A. B[x]
Definitions unfolded in proof :  prop: ℙ,  guard: {T},  subtype_rel: A ⊆r B,  false: False,  implies: P ⇒ Q,  not: ¬A,  and: P ∧ Q,  geo-between: B(abc),  uimplies: b supposing a,  member: t ∈ T,  uall: ∀[x:A]. B[x],  all: ∀x:A. B[x],  basic-geometry-: BasicGeometry-

Latex:
\mforall{}e:BasicGeometry-.  \mforall{}[a,b,c,d:Point].    (B(abd))  supposing  (B(bcd)  and  B(abc)  and  b  \#  c)
