Theorem elntg 28239

Description: The line definition in the Tarski structure for the Euclidean geometry. (Contributed by Thierry Arnoux, 7-Apr-2019.)

**Hypotheses**
Ref	Expression
elntg.1	⊢ 𝑃 = (Base‘(EEG‘𝑁))
elntg.2	⊢ 𝐼 = (Itv‘(EEG‘𝑁))

**Assertion**
Ref	Expression
elntg	⊢ (𝑁 ∈ ℕ → (LineG‘(EEG‘𝑁)) = (𝑥 ∈ 𝑃, 𝑦 ∈ (𝑃 ∖ {𝑥}) ↦ {𝑧 ∈ 𝑃 ∣ (𝑧 ∈ (𝑥𝐼𝑦) ∨ 𝑥 ∈ (𝑧𝐼𝑦) ∨ 𝑦 ∈ (𝑥𝐼𝑧))}))

Distinct variable groups: 𝑥,𝑦,𝑧,𝑁 𝑧,𝑃 Allowed substitution hints: 𝑃(𝑥,𝑦) 𝐼(𝑥,𝑦,𝑧)

Proof of Theorem elntg Dummy variable 𝑖 is distinct from all other variables.
