In order to prove that ∠E = ∠I, we can use the following statements and reasons:
1. Statement: ∠E = ∠FGL
Reason: Opposite angles in a parallelogram are congruent
2. Statement: ∠FGL = ∠KLG
Reason: Alternate interior angles
3. Statement: ∠KLG = ∠I
Reason: Opposite angles in a parallelogram are congruent
4. Statement: ∠E = ∠I
Reason: Transitive property of the equality (∠E = ∠FGL, ∠FGL = ∠KLG and ∠KLG = ∠I, so ∠E = ∠I)
