In the diagram shown, line m is parallel to line n . justine says that ∠3 ∠ 3 and ∠7 ∠ 7 are supplementary angles. is she correct? why or why not?
a. no, because ∠3∠3 is an interior angle and ∠7∠7 is an exterior angle.
b. no, because they are not a linear pair.
c. yes, because ∠3∠3 and ∠8∠8 are congruent corresponding angles, and ∠7∠7 and ∠8∠8 are a linear pair.
d. yes, because ∠3∠3 is acute and ∠7∠7
is obtuse.
