About This Lesson
A dynamic webpage and accompanying worksheet to introduce students to the different angles in parallel lines. They can see the visualization and use it to answer the questions; then allowing them the chance to deduce the relationships for themselves. I have found this really successful in teaching for understanding and have found students recollection of the angle facts is much better when they have seen it in action. Outstanding computer lesson!
A useful GeoGebra applet and subsequent questions to investigate angles and parallel lines. A very good idea tom use GeoGebra for activities like this.
