[i]Line A[/i] and [i]Line B[/i] are parallel lines. They are cut by transversal [i]Line C.[/i] [br][br][br]Do the following:[br][br]1) Drag the blue point under the parallel lines left and right to move the transversal. [br]2) Drag the blue point above the parallel lines to move the transversal left and right. Then drag the blue point under the parallel lines to move the transversal.[br][br](Note: Do not allow the blue points to fall inside the parallel lines or the angles will disappear!)[br][br]Think about the following question as you are moving the blue points on line [i]c[/i].[i][br][b][list=1][*]How does this affect the angles formed by the intersection of [i]Line A[/i] and [i]Line B[/i] with [i]Line C[/i]? [/*][*]Which angles are always congruent? [/*][*]Which angles are always supplementary?[/*][/list][/b][/i][br][br]Answer the questions below.
