Word Version! This is an editable document so you can change the words, descriptions, and pictures to meet your own needs. I also have a PDF version available ($5) in which all you have to do is hit print and hand out to your students to cut and sort! Students take these 30 strips and organize them into 10 groups (word, picture, description). Terms include complementary angles, supplementary angles, angle bisector, congruent, vertical angles, right, straight, obtuse, acute, and linear pair.
