Mathematics | Course : Model Mathematics III (Integrated Pathway)
Domain - Similarity, Right Triangles, and Trigonometry
Cluster - Apply trigonometry to general triangles.
[MIII.G-SRT.D.10] - (+) Prove the Laws of Sines and Cosines and use them to solve problems.
- Law of Cosines
An equation relating the cosine of an interior angle and the lengths of the sides of a triangle. - Law of Sines
Equations relating the sines of the interior angles of a triangle and the corresponding opposite sides.
[MII.G-SRT.C.6] -
Understand that by similarity, side ratios in right triangles are properties of the angles in the triangle, leading to definitions of trigonometric ratios for acute angles.
[MII.G-SRT.C.8] -
Use trigonometric ratios and the Pythagorean Theorem to solve right triangles in applied problems.*
