Product Description
Students will use the proportionality of similar triangles to solve problems. They will narrow their focus to similar right triangles in an applied context to justify repeated use of the same ratios, leading to the development of ratios in special right triangles and the use of the calculator to find trigonometric ratios for other triangles. They will apply these tools to solve problems. This mission is aligned with Common Core State Standards: HSG.SRT.C.6, HSG.SRT.C.8.

The fun stuff:
David and Goliath do battle across a river! David uses bearings and similar triangles to calculate the distance to Goliath, and Goliath tries to find trees that are a perfect height for crossing the river! Similarity, proportionality, special right triangles, trigonometric ratios all converge to solve real world problems! Comprehensive and engrossing!

The zip file includes:
★The mission. (12 pages).
★A two-page Quick Start guide for teachers. Detailed and helpful!
★Selected Answers in pdf form.
★Selected Answers online, password protected. For students to correct at home!

The mission includes:
•Using proportions relating sides of similar triangles to solve problems.
•Demonstration of the practicality of calculating and keeping ratios at hand for certain triangles.
•Ratios of sides in right triangles depends on the measure of a given acute angle.
•Derivation of ratios in special right triangles.
•Sine, cosine and tangent and their application to problems, with and without a calculator.
