Exact ratio triangles
WebGiven the side lengths of a right triangle and one of the acute angles, find the sine, cosine, and tangent of that angle. Find the sine as the ratio of the opposite side to the hypotenuse. Find the cosine as the ratio of the adjacent side to the hypotenuse. Find the tangent as the ratio of the opposite side to the adjacent side. WebDevelopment of the Sine, Cosine, and Tangent ratios by looking at similar triangles. This activity leads into the development of the Trigonometric Table and introduces its use in solving for unknown angles in right triangles. Activity has teacher dashboard correctness checkmarks for several slides.
