Is A=A an example of the Reflexive property of congruence -True -False

jimthompson5910 (jim_thompson5910):

Yes it is true. Think of a mirror and how it reflects the same object. That's how I remember "reflexive".

OpenStudy (anonymous):

just for my own information, since when did "equal" become "congruence"?

jimthompson5910 (jim_thompson5910):

good point, but I think it meant to say \[\Large A \cong A\]

jimthompson5910 (jim_thompson5910):

oh I guess not

jimthompson5910 (jim_thompson5910):

To be completely accurate, satellite73 is right. That equation A = A is the reflexive property of equality. Not congruence.
