Choose the property that justifies the following statement. If AB = CD, then CD = AB.?
A)conditional
B)transitive
C)symmetric
D)reflexive
回答 (2)
In mathematics, an equivalence relative is a binary relation that is reflexive, symmetric and transitive (but not conditional).
• a = a (reflexive property)
• If a = b, then b = a (symmetric property)
• If a = b and b = c, then a = c (transitive property)
It is symmetric property that if AB = CD, then CD = AB.
The answer: C) symmetric
