Unit 4, Lesson 5# Writing and Solving Linear Equations

EngageNY 45 min(s)

Students apply knowledge of geometry to writing and solving linear equations. The purpose is twofold: first, to reinforce what students have learned about geometry, and second, to demonstrate a need for writing and solving an equation in a context that is familiar. Throughout the lesson, students solve mathematical problems that relate directly to what students have learned about angle relationships, congruence, and the triangle sum theorem.
