Theorem ringprop 14283
Description: If two structures have the same ring components (properties), one is a ring iff the other one is. (Contributed by Mario Carneiro, 11-Oct-2013.)
Hypotheses
Ref Expression
ringprop.b  |-  ( Base `  K )  =  (
Base `  L )
ringprop.p  |-  ( +g  `  K )  =  ( +g  `  L )
ringprop.m  |-  ( .r
`  K )  =  ( .r `  L
)
Assertion
Ref Expression
ringprop  |-  ( K  e.  Ring  <->  L  e.  Ring )

Proof of Theorem ringprop
Dummy variables  x  y are mutually distinct and distinct from all other variables.
