Question

(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. Identify the pair of lines used to create the alternate interior angles for each set.
(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. Identify the pair of lines used to create the alternate exterior angles for each set.
(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. Identify the pair of lines used to create the corresponding angles for each set.

Answer 1

A) Alternate interior that are congruent are 15 and 10.   Alternate interior that are not congruent are 27 and 28
b) Alternate exterior that are congruent are 13 and 24.  Alternate exterior that are not congruent are 19 and 22.  
c) Corresponding angles that are congruent are 23 and 18.  Corresponding angles that are not congruent are 11 and 12.
