Theorem qlaxr2i 27876

Description: One of the conditions showing C_ℋ is an ortholattice. (This corresponds to axiom "ax-r2" in the Quantum Logic Explorer.) (Contributed by NM, 4-Aug-2004.) (New usage is discouraged.)

Hypotheses

Ref	Expression
qlaxr2.1	⊢ 𝐴 ∈ Cℋ
qlaxr2.2	⊢ 𝐵 ∈ Cℋ
qlaxr2.3	⊢ 𝐶 ∈ Cℋ
qlaxr2.4	⊢ 𝐴 = 𝐵
qlaxr2.5	⊢ 𝐵 = 𝐶

Assertion
