MD.MA.G. Geometry
Unit 1: Congruence, Proof, and Constructions
HSG-CO.A. Experiment with transformations in the plane.
G.CO.1. Know precise definitions of angle, circle, perpendicular line, parallel line, and line segment, based on the undefined notions of point, line, distance along a line, and distance around a circular arc.
G.CO.1.1. Ability to use mathematical vocabulary accurately.
Unit 2: Similarity, Proof, and Trigonometry
HSG-MG.A. Apply geometric concepts in modeling situations.
G.MG.1. Use geometric shapes, their measures, and their properties to describe objects (e.g., modeling a tree trunk or a human torso as a cylinder).
G.MG.1.1. See the skills and knowledge that are stated in the Standard.
Unit 3: Extending to Three Dimensions
HSG-GMD.A. Explain volume formulas and use them to solve problems.
G.GMD.1. Give an informal argument for the formulas for the circumference of a circle, area of a circle, volume of a cylinder, pyramid, and cone. Use dissection arguments, Cavalieri’s principle, and informal limit arguments.
