Inverse negates both hypothesis and conclusion:
If two lines are not parallel, then the two lines are not in the same plane.
Converse switches the hypothesis and conclusion:
If two lines are in the same plane, then the two lines are parallel.
Contrapositive switches hypothesis and conclusion and negates both:
If two lines are not in the same plane, then the two lines are not parallel.
