All of the lessons we learn in Unit 2 are connected to each other. All of the lessons contain coordinate girds.
Lesson 1 and lesson 2 are connected. Lesson 1 talks about special angle relationships, In lesson 2, you need the angle relationships you learned in lesson 1. So, lesson 2 is connected to lesson 1. Lesson 1 also connects to lesson 3 because lesson 3 goes in-depth about parallel lines, and also lesson 1 shows how parallel lines can form special angle relationships. Lesson 4 connects to lesson 3. Lesson 4 talks about how "lines" on the sphere are not parallel, but the "lines" can be perpendicular, thus referring to the properties of parallel and perpendicular lines stated in lesson 3. Lesson 7 connects to lesson 6. Lesson 6 and lesson 7 both talk about transformations and their properties. They both use the mapping rule. Lesson 8 connects to lesson 6 and lesson 7. Lesson 8 is about tessellations, and in order to create tessellations, you have to use rotations,translations, and reflections, which are all described in lessons 6 and 7. Overall, all the lessons are connected because they all refer to geometry and basic math itself.
