Student Learning Outcomes
Define the features of 2- and 3-dimensional shapes, and use those features to define and classify a variety of shapes.

Describe and use various measurement systems, including comparing various forms of measurement such as English, metric, and nonstandard units.

Define the concepts of length, area, surface area, and volume, then compute them for a variety of 2-D and 3-D shapes.

Use a straightedge and compass to construct 2-D shapes, then use constructions to demonstrate and justify geometric relationships.

Describe conditions for congruence and similarity of triangles, then use those concepts to prove or justify geometric claims.

Describe distance, circles, slope, and perpendicularity both with and without a coordinate system or algebra.

Define, recognize, and apply basic isometries (rigid motions) and dilations in two-dimensional shapes.

Communicate effectively orally and in writing about the concepts and techniques of the course.

Demonstrate knowledge of some geometry learning outcomes in state and national math standards.

Support or refute claims by making logical arguments involving geometric concepts and techniques.
