Question

A = a is an example of which algebraic property?

Answer 1

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 2

Answer: It is the reflexive property of congruence.

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.
