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  $\angle5$  ?

If  $\angle6\cong\angle2$  then  $m\angle6=m\angle2$  .  This means that we can substitute  $m\angle6$  for  $m\angle2$  anywhere!

• Roger that!

• Huh?
