All of the angles are labeled with lower case letters (see the list on the left). Make sure that "a" and "e" are highlighted in red on the list and on the diagram. The numbers on the diagram lists what those angle measurements are. [br][br]What kind of angles are "a" and "e"? (There is only one answer.)

If you move line AB, what do you notice about the measurements of angle "a" and "e"?

If you move line AB, what do you notice about the measurements of angle "c" and "g"?

What conjecture (educated guess) can you make about corresponding angles when formed by PARALLEL lines? (There is only one answer.)

Look at the measurements of angle "c" and "f".[br][br]What conjecture (educated guess) can you make about same side interior angles when formed by PARALLEL lines? (There is only one answer.)

When two parallel lines are cut by a transversal, there is a special relationship between corresponding angles, alternate interior angles, alternate exterior angles and same-side interior angles. [br][br]This relationship is ONLY TRUE if the LINES ARE PARALLEL.[br][br]Fill in the blanks:[br]a) If two parallel lines are cut by a transversal, then corresponding angles are ______________________.[br]b) If two parallel lines are cut by a transversal, then alternate interior angles are ______________________.[br]c) If two parallel lines are cut by a transversal, then alternate exterior angles are ______________________.[br]d)If two parallel lines are cut by a transversal, then same-side interior angles are ______________________.[br][br](Type your 4 answers.)
