Video Learning Notes

In this lesson, students learned to use sine, cosine, and tangent ratios to find missing sides and angles in right triangles. They applied the properties of special right triangles (30°-60°-90° and 45°-45°-90°) and the Pythagorean theorem, including recognizing Pythagorean triples, to solve problems. Students practiced identifying sides relative to angles and choosing appropriate methods to solve real-world and mathematical problems involving right triangles.

Learning Goals

  • Determine the lengths of sides and measures of angles in right triangles by applying sine, cosine, and tangent ratios to solve problems.
  • Apply the relationships in special right triangles (30°-60°-90° and 45°-45°-90°) and the Pythagorean theorem, including Pythagorean triples, to solve problems.
