The correct answer is:
Symmetric Property
Step-by-step explanation:
The symmetric property tells us that if one quantity or measurement is congruent to another, then the second quantity is also congruent to the first. Algebraically it is represented by "If a = b, then b = a."
Basically we can "flip" the equation or congruence statement around the equals or congruence sign. Since that is what happened in this problem, this is the symmetric property.
