Six resources make up the first unit in the Flipped-Mastery series for geometry. In the first lesson, scholars learn how to identify and name points, lines, and planes. They work with four postulates, then practice the skills for naming basic geometric figures. Next, pupils revisit the different angles and their definitions and use their knowledge of an angle bisector to solve algebraic problems. Class members also learn about the Addition Postulate for segments and angles and the names and definitions of special angle pairs. Using the definitions, scholars find the measures of angles in diagrams. For the unit's final, pupils review the vocabulary, formulas, and postulates and use these to solve a problem set that requires learners to apply algebraic skills and provide reasons within a proof. Scholars finish by applying their knowledge to the coordinate plane to find distances and midpoints.
