Ideas for Teachers
As a discussion after having learned about angles on parallel lines, this can make a great starter. Even better if you can let your students play with the activity and come up with their own conjectures. Maybe a homework, with them writing their ideas down for discussion next lesson.
As a starter, reveal one angle, and get them to find all the others.
