Many of the foundations of geometry have been studied informally in mathematics courses prior to Geometry. In this unit, students formalize their understanding of the defined and undefined terms of geometry, as well as investigate and make conjectures involving the relationships among figures.
The measurable attributes of geometric figures are viewed from an algebraic perspective. Students construct parallel and perpendicular lines, as well as segment and angle bisectors using paper folding and technology. Students analyze the results of the rigid transformations of translations, rotations, and reflections. The main focus of instruction is to connect the geometry of rigid transformations and the algebra of transformations in the coordinate plane.
