Both the proposition and its converse (“If corresponding angles formed by a transversal are equal, then the lines are parallel”) are true, representing fundamental geometric properties defining parallel line relationships.
If two lines are parallel, then the corresponding angles formed by a transversal are equal.

Both the proposition and its converse (“If corresponding angles formed by a transversal with two lines are equal, then the lines are parallel”) are true. The proposition follows directly from the parallel lines property, while the converse is established by the corresponding angles axiom, which verifies that two lines cut by a transversal are indeed parallel.
