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:
