Introduction to Parallel Lines - Lesson 4.5
We started today by defining the following:

After that we defined a transversal:

Then, we defined corresponding angles,

alternate interior angles,

and alternate exterior angles.

You should also know how to recognize same side interior angles and same side exterior angles.
We finished by defining parallel lines. Note that parallel lines are different from skew lines, which are to non-coplanar lines that do not intersect.
