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:  Q
Definitions unfolded in proof :  all: x:A. B[x] implies:  Q geo-strict-between: a-b-c and: P ∧ Q member: t ∈ T uall: [x:A]. B[x] subtype_rel: A ⊆B guard: {T} uimplies: supposing a prop: basic-geometry: BasicGeometry

Latex:
\mforall{}e:BasicGeometry.  \mforall{}a,b,c:Point.    (a-b-c  {}\mRightarrow{}  out(a  cb))
