Exterior angle on parallel lines and a Transversal
Parallel lines are lines in a plane which never meet or intersect. The lines have the same slope.
A transversal is a line that intersects at least two other lines.
In this activity you will be able to observe and analyze the eight angles created when a transversal cuts two parallel lines.
Move the transversal by selecting and dragging point C and/or point H.
Analyze the eight angles created when a transversal cuts two parallel lines.
