Geometry Module 1, Topic B, Overview

Learning Math

Constructions segue into Topic B, Unknown Angles, which consists of unknown angle problems and proofs.  These exercises consolidate students’ prior body of geometric facts and prime students’ reasoning abilities as they begin to justify each step for a solution to a problem.  Students began the proof writing process in Grade 8 when they developed informal arguments to establish select geometric facts (8.G.5).
