### Standards

Use trigonometric ratios and the Pythagorean Theorem to solve right triangles in applied problems.
Prove the Laws of Sines and Cosines and use them to solve problems.
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.
