Nuprl Lemma : sq_stable__geo-eq
∀[e:GeometryPrimitives]. ∀[a,b:Point].  SqStable(a ≡ b)
Proof
Definitions occuring in Statement : 
geo-eq: a ≡ b
, 
geo-primitives: GeometryPrimitives

, 
sq_stable: SqStable(P)
, 
uall: ∀[x:A]. B[x]
Definitions unfolded in proof : 
implies: P 
⇒ Q
, 
member: t ∈ T
, 
uall: ∀[x:A]. B[x]
