Nuprl Lemma : geo-congruent-flip2
∀e:EuclideanPlane. ∀[a,b:Point].  ab ≅ ba
Proof
Definitions occuring in Statement : 
euclidean-plane: EuclideanPlane
, 
geo-congruent: ab ≅ cd
, 
geo-point: Point
, 
uall: ∀[x:A]. B[x]
, 
all: ∀x:A. B[x]
Definitions unfolded in proof : 
all: ∀x:A. B[x]
, 
uall: ∀[x:A]. B[x]
, 
member: t ∈ T
, 
euclidean-plane: EuclideanPlane
, 
geo-congruent: ab ≅ cd
, 
not: ¬A
, 
implies: P 
⇒ Q
, 
false: False
, 
subtype_rel: A ⊆r B
, 
guard: {T}
, 
uimplies: b supposing a
, 
and: P ∧ Q
, 
sq_stable: SqStable(P)
