Properties of Parallel Lines applied to Plane Geometry

Here is a list of some of the theorems/postulates that help us define parallel lines:
- converse of corresponding angles postulate
- converse of alternate interior angles theorem
- converse of alternate exterior angles theorem
- converse of same-side interior angles theorem
- parallel postulate

Parallel lines can apply to planes, because planes can be parallel to each other too.
