To arrange the statements and reasons of Olivia's proof in the correct order, we can follow the logical progression of the argument. Here's the ordered sequence:

  1. I am given that quadrilateral MNOP is a parallelogram. I know that opposite sides of a parallelogram are congruent because of the definition of a parallelogram, so MN ≅ OP and MP ∥ NO.

  2. Because of the definition of a parallelogram, I know that opposite sides are congruent. I can say that MN ≅ OP. I now have enough information to say that △MNL ≅ △OPL by the ASA Congruence Theorem.

  3. When I think of the diagonals as transversals cutting parallel lines, I can see that ∠MOP ≅ ∠OMN and ∠NPO ≅ ∠PNM because of the Alternate Interior Angles Theorem.

  4. By the CPCTC Theorem, I know that ML ≅ OL and NL ≅ PL. This shows that MO and NP bisect each other because this is the definition of a bisector.

This sequence logically progresses from stating the properties of the parallelogram to establishing the congruence of triangles and finally concluding that the diagonals bisect each other.
