Oklahoma Academic Standards

OK.G. Geometry (G)
G.RL. Geometry: Reasoning & Logic (G.RL)
G.RL.1. Use appropriate tools and logic to evaluate mathematical arguments.
G.RL.1.1. Understand the use of undefined terms, definitions, postulates, and theorems in logical arguments/proofs.
G.2D. Geometry: Two-Dimensional Shapes (G.2D)
G.2D.1. Discover, evaluate and analyze the relationships between lines, angles, and polygons to solve real-world and mathematical problems; express proofs in a form that clearly justifies the reasoning, such as two-column proofs, paragraph proofs, flow charts, or illustrations.
G.2D.1.7. Apply the properties of congruent or similar polygons to solve real-world and mathematical problems using algebraic and logical reasoning.
G.2D.1.9. Use numeric, graphic and algebraic representations of transformations in two dimensions, such as reflections, translations, dilations, and rotations about the origin by multiples of 90 ̊, to solve problems involving figures on a coordinate plane and identify types of symmetry.
G.3D. Geometry: Three-Dimensional Shapes (G.3D)
G.3D.1. Solve real-world and mathematical problems involving three-dimensional figures.
G.3D.1.2. Use ratios derived from similar three-dimensional figures to make conjectures, generalize, and to solve for unknown values such as angles, side lengths, perimeter or circumference of a face, area of a face, and volume.
