This set of guided notes is a great introduction to rays and angles. The front side stresses the importance of notation and being able to look at geometric diagrams properly. These notes also review the different kinds of angles: acute, obtuse, right and straight angles. The back allows you to introduce the practice of measuring angles with a protractor and labeling angles accordingly. There is also an introduction to the idea of angle bisectors with two practice problems.
The answers are included!
