Tan  $\theta$  = 

•  $\frac{opposite}{adjacent}$  

•  $\frac{opposite}{hypothenuse}$  

•  $\frac{hypothenuse}{adjacent}$  

When do we use the Trigonometric ratios?

• To find the length of one side when given the length of two other sides

• When given one side and an angle

• When only given teh length of a side

•  $\frac{Opposite}{Hypothenuse}$  

•  $\frac{hypothenuse}{Opposite}$  

•  $\frac{Adjacent}{Opposite}$  

•  $\frac{Hypothenuse}{adjacent}$  

Which of the following are true?

• Trigonometric ratios can be used to find a missing side?

• The adjacent side is always in one set position

• The opposite side can be used in the Tan ratio

• The hypothenuse is always the smallest side

 $\cos\theta\ is\ =$  

•  $\frac{opposite}{adjacent}$  

•  $\frac{Adjacent\ }{Hypothenuse}$  

• Adjacent  $\times\$  Opposite

•  $\frac{opposite}{Hypothenuse}$  

As angle z increases which side increases
