If $\angle16=101\degree$ , what is the measure of   $\angle13$ ? How do you know? 

•  $\angle13\ =\ 101$ , because  $\angle13$  and $\angle16$ are alternate exterior angles and alternate exterior angles are congruent. 

•  $\angle13\ =\ 79\degree$ , because  $\angle13$  and $\angle16$ are same-side exterior angles and same-side exterior angles are congruent. 

•  $\angle13\ =\ 79\degree$  , because  $\angle13$  and $\angle16$ are same-side exterior angles and same-side exterior angles are supplementary.

•  $\angle13=101\degree$  , because  $\angle13$  and $\angle16$  are same-side exterior angles and same-side exterior  angles are congruent.
