Answer:
Part a)
1) m<9 and m<28 is a pair of alternate interior angles that are congruent
2) m<9 and m<16 is a pair of alternate interior angles that are not congruent
Part b)
1) m<13 and m<22 is a pair of alternate exterior angles that are congruent
2) m<13 and m<24 is a pair of alternate exterior angles that are not congruent
Part c)
1) m<6 and m<30 is a pair of corresponding angles that are congruent
2) m<6 and m<18 is a pair of corresponding angles that are not congruent
Explanation:
Part a) Using line e as the transversal, name one pair of alternate interior angles that are congruent and one pair of alternate interior angles that are not congruent
1) Using parallel lines a and c and transversal line e
so
m<9 and m<28 is a pair of alternate interior angles that are congruent
2) Using lines a and b and transversal line e
so
m<9 and m<16 is a pair of alternate interior angles that are not congruent
Part b) Using line b as the transversal, name one pair of alternate exterior angles that are congruent and one pair of alternate exterior angles that are not congruent
1) Using parallel lines d and e and transversal line b
so
m<13 and m<22 is a pair of alternate exterior angles that are congruent
2) Using lines d and f and transversal line b
so
m<13 and m<24 is a pair of alternate exterior angles that are not congruent
Part c) Using line f as the transversal, name one pair of corresponding angles that are congruent and one pair of corresponding angles that are not congruent
1) Using parallel lines a and c and transversal line f
so
m<6 and m<30 is a pair of corresponding angles that are congruent
2) Using lines a and b and transversal line f
so
m<6 and m<18 is a pair of corresponding angles that are not congruent
