Learning goals: Section 1: Angle Relationships (Lessons 1–4) • Determine unknown angle measures using facts about complementary, supplementary, and vertical angles. • Write and solve equations for unknown angles in a diagram. Section 2: Drawing Triangles (Lessons 5–8 + Practice Day + Quiz) • Draw triangles given three measures of side lengths or angles. • Determine whether it is possible to draw a unique triangle, more than one triangle, or no triangle given a set of measurements. Section 3: Solid Geometry (Lessons 9–13 + Practice Day) • Describe, compare, and contrast cross sections of prisms and pyramids. • Solve real-world and mathematical problems involving the volume and surface area of right prisms. Materials In all of the lessons in this unit, students should have access to their geometry toolkits, which should contain blank paper, tracing paper, graph paper, colored pencils, scissors, a ruler, a protractor, and an index card. Students may not need all (or even any) of these tools to solve a particular problem. However, to make strategic choices about when to use which tools (MP5), students need to have opportunities to make those choices.
