Corresponding Angles on Parallel Lines

Corresponding angles-Angles that holds the same relative position as another angle somewhere else in the figure. Explore what happens to the corresponding angles when line DE is moved. (To move the line, click a point D/point E and drag it to the left or right)

Name the corresponding angles. For example: Angle y & Angle z Angle k & Angle w
