Trigonometry Ratios Opening routine Determine the missing length in the right triangle using the Pythagorean theorem. Unit 2: Similarity, Proof and Trigonometry Lesson 12 Trigonometry Ratios Objective: Use trigonometric ratios and the Pythagorean Theorem to solve right triangles in applied problems. Essential Question: How can you use the sine and cosine ratios in calculations involving right triangles? Lesson 12 Trigonometry Ratios Vocabulary Hypotenuse: Is the longest side of the right triangle and is the side opposite the right angle. Leg of a right triangle: Either of the sides in a right triangle opposite an acute angle. The legs are the two shorter sides of the triangle. Adjacent leg: Is the leg that is part of the angle. Opposite leg: Is the leg that is not part of the angle. Lesson 12 Trigonometry Ratios Vocabulary Sine: In a right triangle, is the ratio of the length of the side that is opposite that angle to the length of the longest side of the triangle (the hypotenuse). Cosine: In a right triangle, is the ratio of the length of the adjacent side to the angle to the length of the hypotenuse. Tangent: In a right triangle, is the length of the opposite side divided by the length of the adjacent side.
