Mathematics Curriculum Supplement Geometry (G-SRT.C.8) Geometry Mathematics Highly-Leveraged Standard1 G-SRT.C.8 Use trigonometric ratios and the Pythagorean Theorem to solve right triangles in applied problems. Student Learning Targets: Students will be able to: use the trigonometric functions to find the unknown sides of a right triangle. use the trigonometric inverses to find the unknown angles of a right triangle. find all of the unknown sides and angles of a right triangle. solve right triangles in applied problems using trigonometric ratios and the Pythagorean Theorem. Performance Level Descriptors Standard Minimally Proficient Partially Proficient Proficient Highly Proficient The Minimally The Partially Proficient The Proficient student The Highly Proficient Proficient student student student Similarity, Right Triangles and Trigonometry G-SRT.C Solves right triangles Applies the Pythagorean Solves right triangles Models solutions to [8] using the Pythagorean Theorem in real-life and using trigonometric situations, using Theorem. mathematical contexts. ratios and the trigonometric ratios and Pythagorean Theorem in the Pythagorean applied/contextual Theorem, by problems. constructing equations that can be used to solve the problem. Including problems from context. 1 Highly-Leveraged Standards are the most essential for students to learn because they have endurance, leverage and essentiality. This definition for highly-leveraged standards was adapted from the website of Millis Public Schools, K-12, in Massachusetts, USA. http://www.millis.k12.ma.us/services/curriculum_assessment/brochures Specifically for mathematics, the Highly-Leveraged Standards are the Major Content/Clusters as defined by the AZCCRS Grade Level Focus documents. They should encompass a range of at least 65%-75% for Major Content/Clusters and a range of 25%-35% for Supporting Cluster Instruction.
