Targets
- 7A. Use the characteristics of similar figures to justify trigonometric ratios.
- 7B. Define the trigonometric ratios for acute angles in a right triangle and calculate sine and cosine ratios when given two side lengths.
- 7C. Use angle measures to estimate side lengths and side lengths to estimate angle measures.
- 7D. Solve right triangles by finding the measures of all sides and angles.
- 7E. Use the sine, cosine, and tangent, and their inverses to solve for the unknown side lengths and angle measures of a right triangle.
- 7F. Draw right triangles that describe real world problems, including angle of elevation and angle of depression, and label the sides and angles with their given measures.
- 7G. Find the length of a triangle's altitude by using sine function and calculate the area of a triangle using the formula A=(1/2)(a)(b)sinC using any angle of the triangle.
- 7H. Derive the Law of Sines and Law of Cosines and use them to solve real world problems.
- 7I. Distinguish between situation of the Law of Sines and Law of Cosines and use them to find unknown angle measures in right and non-right triangles.
