In the diagram shown, line m is parallel to line n . Justine says that ∠3 ∠ 3 and ∠7 ∠ 7 are supplementary angles. Is she correc
t? 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.
