Nuprl Lemma : geo-strict-between-implies-out2
∀e:BasicGeometry. ∀a,b,c:Point.  (a-b-c ⇒ out(a cb))
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  cb))
