A parallelogram and an incomplete proof are shown.

Place reasons in the table to complete the proof:

**Alternate interior angles are congruent**- If two parallel lines are cut by a transversal, then their pairs of alternate interior angles are congruent
- Alternate interior angles are on alternate sides of the transversal and on the interior of the parallel lines

**Reflexive Property**- A value is equal to itself

**ASA (angle-side-angle)**- If two angles and the included side of one triangle are congruent to two angles and the included side of another

__Corresponding parts of congruent triangles are congruent__- That one is just common sense!
