NAME:_____________________ CC Geometry - Chapter 5 Toolkit Trigonometric Ratios You now have three trigonometric ratios you can use to solve for the missing side lengths and angle measurements in any right triangle. In the triangle below, when the sides are described relative to the angle θ , the opposite leg is y and the adjacent leg is x . The hypotenuse is h regardless of which acute angle is used. Inverse Trigonometry Just as subtraction “undoes” addition and multiplication “undoes” division, the inverse trigonometric functions “undo” the trigonometric functions tangent, sine, and cosine. Specifically, inverse trigonometric functions, they are: _______________ _______________ _______________ This is the inverse, or opposite, of finding the trigonometric ratio from a known angle.
