  1. Right Triangle Trigonometry 9.3.4.2 Apply the trigonometric ratios sine, cosine and tangent to solve problems, such as determining lengths and areas in right triangles and in figures that can be decomposed into right triangles. Know how to use calculators, tables or other technology to evaluate trigonometric ratios.

  2. Guiding question: What is the relationship between the sides and the angles of a right triangle? Trigonometry: Using the sides and angles to find angle and side lengths. 3 Trigonometry Functions • Lesson Obj: IWBAT use the sides and angles of a triangle to find a missing side or angle. • Adjacent: Next to Sine (sin) – uses opposite side and hypotenuse Cosine (cos) – uses adjacent side and hypotenuse Tangent (tan) – uses opposite side and adjacent side.

  3. The 3 trig functions work by where the angle is you are looking at. Do not ever use the right angle! Tip: Put your pencil on the angle you are looking at and find the opposite and adjacent side Hypotenuse is always hypotenuse. Guiding question: What is the relationship between the sides and the angles of a right triangle?

  4. Guiding question: What is the relationship between the sides and the angles of a right triangle? Place your pencil in A, which is the opposite, which is adjacent? Place your pencil on B, which is opposite, which is adjacent?

  5. Guiding question: What is the relationship between the sides and the angles of a right triangle?

  6. Guiding question: What is the relationship between the sides and the angles of a right triangle?

  7. Guiding question: What is the relationship between the sides and the angles of a right triangle? You can also the side measures to find angle measures. Check out this example. • By using on the sides you can figure out an angle measure.

  8. Guiding question: What is the relationship between the sides and the angles of a right triangle? Find the angles here Find the measures of A an B
