Answer:

Michael completed the proof incorrectly.

Step-by-step explanation:

In step 2, Michael incorrectly stated that ∠AKG ≅ ∠AKL due to the vertical angles theorem.

The vertical angles theorem states that when two straight lines intersect, the opposite vertical angles are congruent. In the case of angles AKG and AKL, they are not positioned opposite to each other; rather, they are adjacent. Therefore, they are not congruent by the vertical angles theorem.
