**Geometry Proof: Proving Triangle Congruence**

**Introduction:**
The goal is to prove that triangles \(\triangle EFG\) and \(\triangle EHG\) are congruent given the angle information from the figure.

---

**Given:**
- \(\angle FEG = \angle HEG\)
- \(\angle FGE = \angle HGE\)

**To Prove:**
- \(\triangle EFG \cong \triangle EHG\)

**Proof:**

| **Statements**                       | **Reasons**            |
|--------------------------------------|------------------------|
| 1. \(\angle FEG = \angle HEG\)       | 1. Given               |
| 2. \(\angle FGE = \angle HGE\)       | 2. Given               |
| 3. \(\overline{EG} = \overline{EG}\) | 3. Reflexive property  |
| 4. \(\triangle EFG \cong \triangle EHG\) | 4. (Reason needed)    |

**Conclusion:**
Therefore, \(\triangle EFG\) and \(\triangle EHG\) are congruent by the (selections needed).

**Diagram Explanation:**
The diagram shows a quadrilateral \(EFGH\) with diagonal \(EG\). The given angles are marked to illustrate the given equalities between them, which aids in proving the congruence of \(\triangle EFG\) and \(\triangle EHG\).

**Note to Students:**
To complete the proof, identify the correct congruence criterion (such as ASA, SSS, SAS, etc.) and fill in the missing reason in the proof table.
