Theorem ismrer1 36754

Description: An isometry between ℝ and ℝ↑1. (Contributed by Jeff Madsen, 2-Sep-2009.) (Revised by Mario Carneiro, 22-Sep-2015.)

**Hypotheses**
Ref	Expression
ismrer1.1	⊢ 𝑅 = ((abs ∘ − ) ↾ (ℝ × ℝ))
ismrer1.2	⊢ 𝐹 = (𝑥 ∈ ℝ ↦ ({𝐴} × {𝑥}))

**Assertion**
Ref	Expression
ismrer1	⊢ (𝐴 ∈ 𝑉 → 𝐹 ∈ (𝑅 Ismty (ℝⁿ‘{𝐴})))

Distinct variable group: 𝑥,𝐴 Allowed substitution hints: 𝑅(𝑥) 𝐹(𝑥) 𝑉(𝑥)

Proof of Theorem ismrer1 Dummy variables 𝑘 𝑦 𝑧 are mutually distinct and distinct from all other variables.
