The statement that fills in the blank in the last line of proof is : ∠n ≅ ∠p
Parallelogram
Given that the figure described in the question is a parallelogram the angles in the figure are supplementary angles. Supplementary angles that add up to 180° but not less than 90° and angles ∠n ≤ 180° and ∠p≤180°
Hence we can conclude that the correct option that fills in the blank in the last line of proof is ∠n ≅ ∠p

Attached below is the missing part of the question
A partial proof was constructed given that MNOP is a parallelogram. Parallelogram M N O P is shown. By the definition of a parallelogram, MN ∥ PO and MP ∥ NO. Using MP as a transversal, ∠M and ∠P are same-side interior angles, so they are supplementary. Using NO as a transversal, ∠N and ∠O are same-side interior angles, so they are supplementary. Using OP as a transversal, ∠O and ∠P are same-side interior angles, so they are supplementary. Therefore, __________________ because they are supplements of the same angle
