![## Understanding Vertical Angles and Angle Congruence
### Diagram Explanation
In the diagram, there are two intersecting lines forming four angles at the intersection point O. The angles are labeled as follows:
- Angle AOB
- Angle BOC
- Angle COE
- Angle EOD
The diagram shows these angles with arrows extending from points A, B, C, D, E, and F.
### Problem Statement
We are given:
\[ \angle AOB \cong \angle EOF \]
We need to prove:
\[ \angle BOC \cong \angle DOE \]
### Proof Explanation
To complete the proof, consider the following steps:
1. **Supposition:**
- Suppose that \( \angle BOC \not\cong \angle DOE \).
2. **Vertical Angles Theorem:**
- By the vertical angles theorem, recognize that certain angles are congruent because they are opposite each other when two lines intersect.
3. **Transitive Property:**
- Apply the transitive property where applicable to establish relationships among the angles.
4. **Conclusion:**
- The supposition \( \angle BOC \not\cong \angle DOE \) contradicts the given conditions under the transitive property and vertical angles theorem. Therefore, it must follow that:
\[ \angle BOC \cong \angle DOE \]
### Interactive Element
Two dropdown menus are shown for completing the proof:
- Selecting reasons related to angle congruence, such as vertical angles and transitive properties.
- Final selections that satisfy the conditions of angle congruence given in the problem.
### Buttons
- **Reset:** Clears current selections and allows a fresh start.
- **Next:** Proceeds to the following question or activity after completing the proof correctly.
