In this unit, students will extend their study of right triangles to determine side lengths or acute angle measures that cannot be found using the Pythagorean theorem and/or properties of similar triangles. This will involve the development and use of the sine, cosine and tangent ratios. The tangent ratio will be explored first since it relates to situations involving angles of inclination. Students will develop a better understanding of the ratio and an appreciation of its practical value by determining the height of a variety of objects. Students will then proceed to work with right triangles involving sine and cosine ratios. When solving right triangle problems, they will determine which ratio is appropriate by the information given. They will assess the reasonableness of their answers and identify errors in both their problem solving approach and in their subsequent calculations.
