Geometry with Data Analysis
35. Discover and apply relationships in similar right triangles.
a. Derive and apply the constant ratios of the sides in special right triangles (45o-45o-90o and 30o-60o-90o).
b. Use similarity to explore and define basic trigonometric ratios, including sine ratio, cosine ratio, and tangent ratio.
c. Explain and use the relationship between the sine and cosine of complementary angles.
d. Demonstrate the converse of the Pythagorean Theorem.
e. Use trigonometric ratios and the Pythagorean Theorem to solve right triangles in applied problems, including finding areas of regular polygons.
