Preparation
Lesson Narrative
In this lesson, students practice writing and solving equations of the form
The angles used in this lesson connect to earlier work with supplementary, complementary, and vertical angles, giving additional opportunities to build fluency with these concepts.
- Determine whether a given equation represents the relationship between angles shown in a diagram.
- Solve an equation that represents a relationship between angle measures, and explain (in writing and using other representations) the reasoning.
- Write an equation of the form
