We assume that, since the lines are parallel, Corresponding Angles are congruent - for example  $\angle5\cong\angle1$  .  Check any box with Corresponding Angles.

•  $\angle1\ and\ \angle2$  
  

•  $\angle2\ and\ \angle6$  
  

•  $\angle4\ and\ \angle8$  
  

•  $\angle3\ and\ \angle7$

If  $\angle5\ and\ \angle4$  are one pair of Alternate Interior Angles, name the other pair of Alternate Interior Angles

•  $\angle3\ and\ \angle2$  

•  $\angle6\ and\ \angle8$  

•  $\angle3\ and\ \angle6$  

•  $\angle1\ and\ \angle9$
