∀[rv:InnerProductSpace]. ∀[a,b,c,d:Point]. (ab=cd ∈ ℙ)
Proof
Definitions occuring in Statement :
ip-congruent: ab=cd,
inner-product-space: InnerProductSpace,
ss-point: Point,
uall: ∀[x:A]. B[x],
prop: ℙ,
member: t ∈ T
Definitions unfolded in proof :
uall: ∀[x:A]. B[x],
member: t ∈ T,
ip-congruent: ab=cd,
subtype_rel: A ⊆r B,
guard: {T},
uimplies: b supposing a
