#### MAT-HS.G-SRT.07

 MAT-HS Targeted Standards(G) Concept: Geometry(SRT) Domain: Similarity, Right Triangle, and TrigonometryCluster: Define trigonometric ratios and solve problems involving right triangles. MAT-HS.G-SRT.07 Explain and use the relationship between the sine and cosine of complementary angles.

## Student Learning Targets:

### Knowledge Targets

• I can show that the side ratios are the same in similar right triangles, which leads to the definition of trigonometric ratios for acute angles.

### Reasoning Targets

• I can explain the relationship between the sine and cosine of complementary angles.

### Skills (Performance) Targets

• I can use the relationship between the sine and cosine of complementary angles.

• I can
• I can

## Proficiency Scale

 Score Description Sample Activity 4.0 In addition to Score 3.0, the student demonstrates in-depth inferences and applications regarding more complex material that go beyond end of instruction expectations. - 3.5 In addition to Score 3.0 performance, the student demonstrates in-depth inferences and applications regarding the more complex content with partial success. 3.0 “The Standard.” The student demonstrates no major errors or omissions regarding any of the information and processes that were end of instruction expectations. - 2.5 The student demonstrates no major errors or omissions regarding the simpler details and processes (Score 2.0 content) and partial knowledge of the more complex ideas and processes (Score 3.0 content). 2.0 The student demonstrates no major errors or omissions regarding the simpler details and processes but exhibits major errors or omissions regarding the more complex ideas and processes (Score 3.0 content). - 1.5 The student demonstrates partial knowledge of the simpler details and processes (Score 2.0 content) but exhibits major errors or omissions regarding the more complex ideas and procedures (Score 3.0 content). 1.0 With help, the student demonstrates a partial understanding of some of the simpler details and processes (Score 2.0 content) and some of the more complex ideas and processes (Score 3.0 content). - 0.5 With help, the student demonstrates a partial understanding of some of the simpler details and processes (Score 2.0 content) but not the more complex ideas and processes (Score 3.0 content). 0.0 Even with help, the student demonstrates no understanding or skill. -
