The statement "If two parallel lines are cut by a transversal, then the alternate interior angles are congruent" is known as the **Alternate Interior Angles Theorem**.

Here's a brief explanation of the other terms mentioned:

- **Converse of the Corresponding Angles Postulate**: If two lines are cut by a transversal and the corresponding angles are congruent, then the lines are parallel.

- **Same-Side Interior Angles Theorem**: If two parallel lines are cut by a transversal, then the same-side interior angles are supplementary (add up to 180 degrees).

- **Converse of the Alternate Interior Angles Theorem**: If two lines are cut by a transversal and the alternate interior angles are congruent, then the lines are parallel.

So, to summarize, the original statement describes the **Alternate Interior Angles Theorem**.
