trigonometry trigonometry : the study of the properties of triangles trigonometric ratio trigonometric ratio : ratio of measures of two sides of a right triangle tangent tangent : in a right triangle, the ratio of the leg opposite the acute angle to the leg adjacent to the acute angle

3
Definition A C B hypotenuse leg adjacent to A leg opposite A

4
Ex 1 A C B 41 40 9 Find tan A and tan B.

5
Ex 2 P R Q 5 4 3 Find tan P and tan Q.

6
Tangents with Angle Measurements F D E 70 45 m The tangent of an angle depends on the angle, not the size of the triangle. Find the measurement of DF. Ex 3
