The two triangles shown in the image appear to be triangles \( \triangle DCB \) and \( \triangle NOP \), and they are likely congruent based on the markings provided. Let's break down the proof and the steps needed for the flowchart.

### Identifying the Congruence

From the image, we see the following information:
1. **Markings on the sides**: Each triangle has two sides marked as congruent:
   - \( \overline{CB} \cong \overline{OP} \)
   - \( \overline{CD} \cong \overline{ON} \)
   
2. **Right angles**: Both triangles have a right angle at \( \angle DCB \) and \( \angle NOP \).

This suggests that the triangles may be congruent by the **SAS (Side-Angle-Side) Congruence Postulate**, where two sides and the included angle (in this case, the right angle) are congruent between the two triangles.

### Flowchart Proof

Here’s how the flowchart proof would proceed:

1. **Statement**: \( \overline{CB} \cong \overline{OP} \)  
   **Reason**: Given

2. **Statement**: \( \overline{CD} \cong \overline{ON} \)  
   **Reason**: Given

3. **Statement**: \( \angle DCB \cong \angle NOP \)  
   **Reason**: Both are right angles (Given or definition of right angles)

These three statements establish congruence by **SAS (Side-Angle-Side)**.

4. **Final Conclusion**:  
   \( \triangle DCB \cong \triangle NOP \)  
   **Reason**: SAS Congruence Postulate

This is how the flowchart proof would be structured.

### Tip:
When using the SAS postulate, ensure that the angle included between the two sides being compared is congruent, as it is a key element of this proof strategy.

Determine if the two triangles DCB and NOP are necessarily congruent. If so, prove using a flowchart.
