Similarity+with+trig+ratios

Goals:

__**Special Right Triangles**__ 1. Given a collection of similar special right triangles. dixcover the ratios of adjacent, oppsite and hypotenuse, for a given angle, are the same. 2. Extend ideas in Goal 1 to include all similar right triangles. 3. Define trigonometric ratios in terms of the sides of a triangle, with relation to an angle.

__**Sine and cosine with special right triangles.**__ 1. Discover and explain the relationship between sine and cosine of complimentary angles. 2. Recognize when it's appropriate to use an angle or its complement to solve a problem. 3. Use calculators to compute trigonometric ratios. 4. Using a given angle and side, use trig ratios to solve for a missing side length of a right triangle. 5. Using two given sides, find a missing angle measure of a right triangle. 6. Using trig ratios and the Pythagorean Theorem, solve any right triangle.
