Question

1. tracy is trying to justify a step in her paragraph proof. what is the property that she should use?

\\( \overline { a b } \cong \overline { a b } \\)
transitive property of congruence
reflexive property of congruence
eality of congruence property
symmetric property of congruence

Explanation:

The Reflexive Property of Congruence states that any geometric figure is congruent to itself. Here, \(\overline{AB}\) is congruent to \(\overline{AB}\), which fits this property. The Transitive Property would involve three figures (\(A\cong B\) and \(B\cong C\) implies \(A\cong C\)). The Symmetric Property would be if \(A\cong B\) then \(B\cong A\). There's no "Equality of Congruence Property" in standard geometric congruence properties.

Answer:

Reflexive Property of Congruence
