Question
If 
then 
- Reflexive property of congruence
- Symmetric property of congruence
- Transitive property of congruence
Hint:
It is symmetric as a->b then b->a
The correct answer is: Symmetric property of congruence
If then
Here first element is linked with second
and second is linked with first
SO, it follows from the property of Symmetric relation.
In math, the symmetric relation is the relationship between two or more elements such that if the first element is associated with the second then the second element is also linked to the first element in a similar fashion.
