Nuprl Lemma : geo-sas2

e:BasicGeometry. ∀a,b,c,A,B,C:Point.  bc ≅ BC supposing (ab ≅ AB ∧ ac ≅ AC) ∧ bac ≅a BAC


Proof




Definitions occuring in Statement :  geo-cong-angle: abc ≅a xyz basic-geometry: BasicGeometry geo-congruent: ab ≅ cd geo-point: Point uimplies: supposing a all: x:A. B[x] and: P ∧ Q
Definitions unfolded in proof :  all: x:A. B[x] uimplies: supposing a member: t ∈ T and: P ∧ Q geo-cong-angle: abc ≅a xyz exists: x:A. B[x] basic-geometry: BasicGeometry implies:  Q uall: [x:A]. B[x] cand: c∧ B subtype_rel: A ⊆B prop: guard: {T} geo-congruent: ab ≅ cd not: ¬A false: False
