11) Given the two parallel lines cut by a transversal,

What is the measure of $\angle4$  if  $m\angle8=76\degree$  ?

10)Given the two parallel lines cute by a transversal,

What is the measure of  $\angle5$  ?

3) Given the following two parallel lines cut by a transversal.

Which pair of angles represents alternate interior angles?

•  $\angle3$  and $\angle8$  
  

•  $\angle7$  and $\angle2$  

•  $\angle7$  and $\angle8$  

•  $\angle4$  and $\angle8$  

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

•  $\angle3\ and\ \angle2$  

•  $\angle6\ and\ \angle8$  

•  $\angle3\ and\ \angle6$  

•  $\angle1\ and\ \angle9$  

Find y.

• 130
• 50

Find  $m\angle1.$  

•  $131\degree$  

•  $180\degree$  

•  $49\degree$  

Find the measure of each angle indicated. 

• 139°
• 66°
• 138°
• 116°

If these lines are parallel,  $\angle2\cong\angle6$ because they're Corresponding Angles.
What is true about  $\angle2\ and\ \angle4$  ?

• They are congruent

• They form vertical angles

• They form a linear pair

• They are non-adjacent angles
