Theorem cvrlt 36410
Description: The covers relation implies the less-than relation. (cvpss 30065 analog.) (Contributed by NM, 8-Oct-2011.)
Hypotheses
Ref Expression
cvrfval.b 𝐵 = (Base‘𝐾)
cvrfval.s < = (lt‘𝐾)
cvrfval.c 𝐶 = ( ⋖ ‘𝐾)
Assertion
Ref Expression
cvrlt (((𝐾𝐴𝑋𝐵𝑌𝐵) ∧ 𝑋𝐶𝑌) → 𝑋 < 𝑌)

Proof of Theorem cvrlt
Dummy variable 𝑧 is distinct from all other variables.
