Wrong statement. Parallel lines don't always make vertical angles without the transversal, the line that passes through these lines. Without the transversal, we can't make the conclusion that parallel lines form vertical angles.
A valid conclusion would be that a tautology is true.
If the lines are perpindicular then each pair of vertical angles are supplementary
A+
If two angles are vertical then they are congruent.
no vertical angles are equal
Yes, vertical angles do have the same measures.

Vertical angles must necessarily be congruent, however congruent angles do not necessarily have to be vertical angles. An example of congruent angles which are not vertical angles are the 3 interior angles of an equilateral triangle. These angles do not share the same vertex yet they are congruent.
If the lines are perpindicular then each pair of vertical angles are supplementary
they are congruent: exactly equal
A+
