Identifying Properties Which property is shown? If m∠ABC = m∠CBD, then m∠CBD = m∠ABC reflexive property substitution property symmetric property transitive property

Symmetric property

Step-by-step explanation:

In this question, we are given a set of options to choose the correct answer from which gives the definition of the property in the question.

The correct answer here is the symmetric property. So why is this correct?

In proper terms, we refer to this property as the symmetric property of congruence.

It is a way of referring to the fact that when writing the way two congruent angles are equal to each other by the property of congruence, we can move in either of the two directions.

Either way we write, we are absolutely correct to indicate that both angles are equal due to the property of congruence.
