A=A or a=a is an example of the reflexive property, it's like looking in a mirror of oneself, hence the name of the property.
Answer: It is the reflexive property of congruence.
Step-by-step explanation:
Since we have given that
A = a
It is the property of reflexive congruence, in which any two terms are congruent to itself.
Here, we have A = a
And a is congruent to itself obviously.
So, it is the reflexive property of congruence.
