Nuprl Lemma : circle-strict-overlap-implies-overlap
∀g:GeometryPrimitives. (BasicGeometryAxioms(g) ⇒ (∀a,b,c,d:Point.  (StrictOverlap(a;b;c;d) ⇒ Overlap(a;b;c;d))))
Proof
Definitions occuring in Statement : 
circle-strict-overlap: StrictOverlap(a;b;c;d), 
circle-overlap: Overlap(a;b;c;d), 
basic-geo-axioms: BasicGeometryAxioms(g), 
geo-primitives: GeometryPrimitives, 
geo-point: Point, 
all: ∀x:A. B[x], 
implies: P ⇒ Q
Definitions unfolded in proof : 
all: ∀x:A. B[x], 
implies: P ⇒ Q,

squash: ↓T, 
exists: ∃x:A. B[x], 
and: P ∧ Q, 
member: t ∈ T, 
cand: A c∧ B,

prop: ℙ, 
guard: {T}, 
basic-geo-axioms: BasicGeometryAxioms(g)
Latex:
\mforall{}g:GeometryPrimitives
    (BasicGeometryAxioms(g)  {}\mRightarrow{}  (\mforall{}a,b,c,d:Point.    (StrictOverlap(a;b;c;d)  {}\mRightarrow{}  Overlap(a;b;c;d))))
