Lesson: The Sine Ratio Mathematics

Students will be able to

• use right triangles to find sine ratios,
• use special right triangles to find the sine ratios for , , and ,
• use the sine ratio to find missing lengths in right triangles,
• use the inverse sine ratio to find missing angle measures in right triangles,
• solve more complex problems, such as using the sine ratio or inverse sine ratio in combination with the Pythagorean theorem, simple 2D shape properties, or coordinate geometry.
