## OPS Geometry Content Standards

 Number Content Standard/Skill and Knowledge Statements 01 Use the concepts of congruence and similarity to name, label, describe, determine missing parts of various figures, and to complete proofs. 02 Apply properties related to parallelism and perpendicularity to two- and three-dimensional figures, and solve equations and inequalities based upon these properties. 03 Solve problems involving the properties of polygons, both regular and non-regular. 04 Solve problems involving right triangles using the Pythagorean Theorem, special right triangles, and right triangle trigonometry. 05 Solve problems related to circles, including area, circumference, arc length, arc measure, and central angles, as well as problems using the properties of tangents, secants, and chords and the angles they create. 06 Apply formulas for measurement of perimeter, area, surface area, and volume. 07 Use a variety of methods of proof, including two-column proof, indirect proof, and paragraph proof. 08 Use coordinate geometry to solve distance, midpoint, slope, and circle problems. 09 Translate and transform two-dimensional figures in a plane.
