Nuprl Lemma : geo-strict-between-implies-out
∀e:BasicGeometry. ∀a,b,c:Point. (a-b-c ⇒ out(a bc))
Proof
Definitions occuring in Statement :
geo-out: out(p ab),
basic-geometry: BasicGeometry,
geo-strict-between: a-b-c,
geo-point: Point,
all: ∀x:A. B[x],
implies: P ⇒ Q
Definitions unfolded in proof :
all: ∀x:A. B[x],
implies: P ⇒ Q,
geo-strict-between: a-b-c,
and: P ∧ Q,
member: t ∈ T,
uall: ∀[x:A]. B[x],
subtype_rel: A ⊆r B,
guard: {T},
uimplies: b supposing a,
prop: ℙ,
basic-geometry: BasicGeometry
Latex:
\mforall{}e:BasicGeometry. \mforall{}a,b,c:Point. (a-b-c {}\mRightarrow{} out(a bc))
