Nuprl Lemma : basic-axioms-imply_between2
∀e:EuclideanPlaneStructure. (BasicGeometryAxioms(e) ⇒ (∀a,b1,b2,c:Point. (b1 ≡ b2 ⇒ B(ab1c) ⇒ B(ab2c))))
Proof
Definitions occuring in Statement :
euclidean-plane-structure: EuclideanPlaneStructure,
basic-geo-axioms: BasicGeometryAxioms(g),
geo-eq: a ≡ b,
geo-between: B(abc),
geo-point: Point,
all: ∀x:A. B[x],
implies: P ⇒ Q
Definitions unfolded in proof :
all: ∀x:A. B[x],
implies: P ⇒ Q,
member: t ∈ T,
and: P ∧ Q,
subtype_rel: A ⊆r B,
basic-geo-axioms: BasicGeometryAxioms(g),
uall: ∀[x:A]. B[x],
prop: ℙ,
geo-between: B(abc),
cand: A c∧ B,
not: ¬A,
geo-lsep: a # bc,
or: P ∨ Q,
false: False,
geo-ge: ab ≥ cd,
guard: {T},
geo-sep: a # b,
geo-eq: a ≡ b
