For each angle below, determine the quadrant in which the terminal side of the angle is found and find the corresponding reference angle $\bar{\theta}$.

 1 $\theta = \frac { 11 \pi } { 3 }$ is found in quadrant and $\bar{\theta}=$ . 2 $\theta = \frac { 13 \pi } { 4 }$ is found in quadrant and $\bar{\theta}=$ . 3 $\theta = \frac { 23 \pi } { 6 }$ is found in quadrant and $\bar{\theta}=$ . 4 $\theta = 4$ is found in quadrant and $\bar{\theta}=$ .
