a and b are parallel lines. They are cut by transversal [i]c[/i]. [br][br][i]A [b]transversal [/b]is a line that passes through two lines at two distinct points.[/i] Line [i]c[/i] graphed below is a [i][b]transversal[/b][/i].[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].[br][br][i]How does moving the transversal affect the angles formed by the intersection of a and b with c? [/i][br][br]Answer the questions below.
Which angles are always equal? Describe the angles position around line a and line b. Use vocabulary words in your explanation.
Which angles are always supplementary? Describe the angles positions around line a and line b. Use vocabulary words!
