Identify the given arc measures

\[

$$\begin{aligned} &m\widehat{EH} = 115^\circ \\ &m\widehat{GF} = 115^\circ \end{aligned}$$

\]

Apply the Congruent Chords Theorem

\[

$$\begin{aligned} &m\widehat{EH} = m\widehat{GF} \implies \overline{EH} \cong \overline{GF} \end{aligned}$$

\]

Match with the given options

\[
\text{The segments } \overline{FG} \text{ (or } \overline{GF}\text{) and } \overline{EH} \text{ are congruent.}
\]
