Complementary and Supplementary Angles Practice
This is a 5 page PDF document on complementary and supplementary angles for advanced 7th and 8th grade students and all 9-12 students. Many students have a hard time remembering the difference between complementary and supplementary angles; i.e. which one adds up to 90 degrees, etc. Included is an eye-catching poster can be added to your word wall so that they remember that just like in the alphabet C comes before S, 90 comes before 180 so complementary angles add up to 90 and supplementary to 1
