Drag the points C and B to investigate angle relationships formed by two non-parallel lines and a transversal. Which angles are [i][b]congruent[/b][/i]? Which angles are [b][i]supplementary[/i][/b]?
Select the types of angle pairs which are congruent, if any.
Select the types of angle pairs which are supplementary, if any.
The blue line and the black line are parallel. Drag point B to investigate angle relationships formed by two parallel lines and a transversal. Which angles are [b][i]congruent[/i][/b]? Which angles are [b][i]supplementary[/i][/b]? Compare the angle relationships when the lines are parallel to the example above where the lines were not parallel. What is similar? What is different?
Select the types of angle pairs which are congruent, if any.
Select the types of angle pairs which are supplementary, if any.
