Geometry EX, Part 1 of 2

This course formalizes what students learned about geometry in the middle grades with a focus on reasoning and making mathematical arguments. Mathematical reasoning is introduced with a study of triangle congruence, including exposure to formal proofs and geometric constructions. Moving on to other shapes, students justify and derive various formulas for circumference, area, and volume as well as cross-sections of solids and rotations of two-dimensional objects. The course closes with a study of set theory and probability to make decisions informed by data analysis.
