--- | ---
1. ∠1≅∠5 | 1. Given
2. ∠2≅∠5 | 2. Vertical Angles Theorem
3. ∠1≅∠2 | 3. Transitive Property of Equality (since ∠1≅∠5 and ∠2≅∠5, we have ∠1≅∠2)
4. ∠1≅∠4 | 4. Vertical Angles Theorem (since ∠1 and ∠4 are vertical angles)
5. ∠2≅∠4 | 5. Transitive Property of Equality (since ∠1≅∠2 and ∠1≅∠4, we have ∠2≅∠4)

This completes the proof.
