This image shows a geometric proof involving triangles, where the goal is to prove that ∠CAB ≅ ∠CBA (angle CAB is congruent to angle CBA). Let me summarize and break down the proof shown in the table:

### Proof Steps:

1. **Statement:** \( AD \cong DB \)  
   **Reason:** Given  
   This shows that segment AD is congruent to segment DB, meaning AD and DB are equal in length (this is given information).

2. **Statement:** \( \angle CAD \cong \angle CBD \)  
   **Reason:** Given  
   This means that the angles ∠CAD and ∠CBD are congruent, which is also given.

3. **Statement:** \( \overline{AC} \cong \overline{AC} \)  
   **Reason:** Reflexive Property  
   This uses the reflexive property, stating that any segment is congruent to itself. Here, segment AC is congruent to itself.

4. **Statement:** \( \triangle ACB \cong \triangle ACB \)  
   **Reason:** Reflexive Property  
   Similarly, triangle ACB is congruent to itself (though this seems repetitive given the earlier step).

5. **Statement:** \( \triangle ADB \) is an isosceles triangle  
   **Reason:** The triangle has two congruent sides  
   Since \( AD \cong DB \), triangle ADB is isosceles.

6. **Final Statement:** \( \angle CAB \cong \angle CBA \)  
   **Reason:** Reflexive Property  
   This is the key statement of the proof: angles CAB and CBA are congruent. This seems to be based on the property of isosceles triangles, where the base angles are congruent.

### Explanation:
- The proof relies on the properties of isosceles triangles, where if two sides of a triangle are congruent, the angles opposite those sides must also be congruent.
- Reflexive properties are applied to justify that segments or angles are congruent to themselves.

4. How do the base angles of an isosceles triangle behave?
5. Can the same proof approach be used for triangles that are not isosceles?

### Tip:
In geometry proofs, clearly stating the reason behind each step (like using given information or congruence properties) ensures the logical flow and correctness of the argument.

Prove: ∠CAB ≅ ∠CBA in the given geometric proof involving an isosceles triangle and congruent angles.

In this geometric proof, we prove that ∠CAB is congruent to ∠CBA using the properties of isosceles triangles and the reflexive property. Step-by-step reasoning is provided, suitable for students in Grades 9-10 studying congruent angles and geometric theorems.
