Solution
Solution Steps
To determine which theorems affirm that $\triangle G C B \cong \triangle H C B$, we need to identify the criteria for triangle congruence. The given information suggests that $\overline{B C}$ is congruent to itself, and we need to consider other sides and angles to apply the appropriate congruence theorems.
Step 1: Identify Given Information
We are given that \(\overline{BC} \cong \overline{BC}\). This means that side \(BC\) is congruent to itself.
Step 2: Determine Applicable Congruence Theorems
To determine which theorems affirm that \(\triangle GCB \cong \triangle HCB\), we need to consider the criteria for triangle congruence. The possible congruence theorems are:
Side-Side-Side (SSS) Congruence
Angle-Side-Angle (ASA) Congruence
Side-Side-Angle (SSA) Congruence
Side-Angle-Side (SAS) Congruence
Step 3: Apply the Given Information
Given that \(\overline{BC}\) is congruent to itself, we need to consider other sides and angles to apply the appropriate congruence theorems. The most likely applicable theorems based on the given information are:
Side-Side-Side (SSS) Congruence
Side-Angle-Side (SAS) Congruence
Final Answer
The theorems that affirm \(\triangle GCB \cong \triangle HCB\) are:
\[
\boxed{\text{A: Side-Side-Side Congruence}}
\]
\[
\boxed{\text{D: Side-Angle-Side Congruence}}
\]
