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

What is the measure of  $\angle5$  ?

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

•  $\angle1\ and\ \angle2$  
  

•  $\angle2\ and\ \angle6$  
  

•  $\angle4\ and\ \angle8$  
  

•  $\angle3\ and\ \angle7$  
  

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

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

Find the missing angle.  Find x.

• 20^o
• 70^o
• 160^o
• 180^o

Vertical angles are always

• acute
• total 180 degrees
• congruent (equal measures)
• adjacent angles

 $\angle3$  and   $\angle7$  are ___.  

• Alternate Interior Angles

• Alternate Exterior Angles

• Same-side Interior Angles

• Corresponding Angles

• None of these

Find the measure of the missing angle.

• 90^o
• 10⁰
• 130^o
• 50^o

5) True or False.

If the following parallel lines are cut by a transversal, would 
 $\angle2$  and  $\angle6$   be corresponding?

• True

• False

 $\angle5$  and  $\angle6$  are ___.  

• Alternate Interior Angles

• Alternate Exterior Angles

• Same-side Interior Angles

• Corresponding Angles

• None of these

Which of the angle pairs below is a pair of same-side interior angles?  

•  $\angle7\$  and  $\angle6$  

•  $\angle2\$  and  $\angle6$  

•  $\angle2\$  and  $\angle4$  

•  $\angle8\$  and  $\angle5$
