Oct 13, 2025 by wbrum.org 33 views

The reflexive property of congruence is a fundamental concept in geometry that states that any geometric figure is congruent to itself. This property is essential in establishing the relationships between different geometric figures and is used extensively in various mathematical proofs and theorems. In this article, we will explore the reflexive property of congruence and examine which statement is an example of this property.

What is the Reflexive Property of Congruence?

The reflexive property of congruence is a property that states that any geometric figure is congruent to itself. This means that if we have a geometric figure, say a triangle, it is congruent to itself. This property is denoted by the symbol ≅ and is read as "is congruent to."

Example of the Reflexive Property of Congruence

To illustrate the reflexive property of congruence, let's consider an example. Suppose we have a triangle EFG. We can say that triangle EFG is congruent to itself, denoted by the symbol ≅. This is an example of the reflexive property of congruence.

Statement Analysis

Now, let's analyze the given statements to determine which one is an example of the reflexive property of congruence.

A. $\triangle EFG \cong \triangle EFG$

This statement directly states that triangle EFG is congruent to itself. This is an example of the reflexive property of congruence, as it states that a geometric figure is congruent to itself.

B. If $\triangle EFG \cong \triangle HJK$ , then $\triangle HJK \cong \triangle EFG$

This statement is an example of the symmetric property of congruence, not the reflexive property. The symmetric property states that if two geometric figures are congruent, then the order of the figures does not matter.

C. If $\triangle EFG \cong \triangle HJK$ , then $\triangle EFG \cong \triangle EFG$

This statement is also an example of the symmetric property of congruence, not the reflexive property. The symmetric property states that if two geometric figures are congruent, then the order of the figures does not matter.

Conclusion

In conclusion, the correct answer is statement A. $\triangle EFG \cong \triangle EFG$ . This statement directly states that triangle EFG is congruent to itself, which is an example of the reflexive property of congruence.
