Lesson 18 use complementary and vertical angles answers. It gives examples of identifying these angle pairs in diagrams. 16. It also provides practice problems for finding missing angle measures using properties of these angle pairs and relationships between angles. both complementary and supplementary A quilter uses complementary angles to cut fabric. NYS Learning Standards: 7. Let's Practice: Using the diagram below, list several pairs of supplementary and vertical angles. What do you notice about the angle measures of complementary angles, supplementary angles, and vertical angles? Lesson 8. Then solve problems 1–5. In the diagram below, angles 1 and 2 are vertical because they form an X and are opposite angles in that X.
