Parallel Lines Intersected by a Transversal

[b]The lines a and b are parallel, cut by transversal c. Drag the blue points on c to move the transversal. [/b][br] 1. How does this affect the angles formed by the intersection of a and b with c? [br] 2. Which angles are always congruent? [br] 3. Which angles are always supplementary?
