Parallel Lines Cut by a Transversal

Objectives: Students will be able to…[br]• Identify corresponding, alternate exterior, and alternate interior angles.[br]• Understand theorems about angles created by parallel lines cut by a transversal. [br] [br]The theorems we are looking at are [br]• Corresponding Angles Postulate[br]• Alternate Interior Angles Theorem[br]• Alternate Exterior Angles Theorem[br]What do you notice about the corresponding angles?[br]What do you notice about the alternate interior angles?[br]What do you notice about the alternate exterior angles?[br]Do you think this would be true if the two lines were not parallel? Why? [br]Can you come up with an explanation why this proves the theorems and postulate?[br][br]If two corresponding angles were labeled 3x+4 and 1/2x+8, what would be the value of x? What are the angles values?[br][br]Create a problem that can be solved using corresponding angles postulate.
