Try using these interactive quizzes to help you learn your angle rules with parallel lines.
This first set of questions will have you look at an image and try and select the two angles which match the rule in a multiple choice format.
These questions will have you look closely at the definitions of the different angle rules. Remember that the iff statement means that the condition is a requirement for the angle rule to be true. The iff statement can also be used in the future as a way to test to see if two lines are parallel to one another.
