Answers:

  • (a) 1 and 8
  • (b) 3 and 6
  • (c) 4 and 8

=================================

Step-by-step explanation

  • (a) The angles are outside of the "parallel" train tracks. This is what the term "exterior" means. The angles are on opposite sides of the transversal line, which is what the "alternate" refers to. The other alternate exterior pair is angle 2 with angle 7.
  • (b) This time the angles are inside the train tracks due to "interior". They alternate on either side of the transversal. The other alternate interior pair is angle 4 with angle 5.
  • (c) These angles are in the same corner for each four-corner angle arrangement. This is the northeast corner. Corresponding angles match up when applying a geometric translation (aka shifting left/right and up/down). The other 3 corresponding angle pairs are: 1 and 5, 2 and 6, 3 and 7.
