Category Archives: Geometry c 9 A-B Similarity, Proof, and Trigonometry

(9) Similarity, proof, and trigonometry. The student uses the process skills to understand and apply relationships in right triangles. The student is expected to:
(A) determine the lengths of sides and measures of angles in a right triangle by applying the trigonometric ratios sine, cosine, and tangent to solve problems; and
(B) apply the relationships in special right triangles 30o-60o-90o and 45o-45o-90o and the Pythagorean theorem, including Pythagorean triples, to solve problems.
