Unit 5- Right Triangle Trigonometry
- Students should be able to use similarity to establish sine, cosine, and tangent ratios.
- Students should be able to verify and apply the relationship between cofunctions, sin(𝛳) = cos(90°- 𝛳) and cos(𝛳) = sin(90°- 𝛳).
- In seventh grade, students write and solve equations using supplementary, complementary, vertical, and adjacent angles.
- Students should be able to use sine, cosine, and tangent to solve real-life problems that require them to find missing side and angle measurements.
