Answer:
1. B and F
2. A and G
3. 0
4. B and D, C and E, D and F, E and G
Step-by-step explanation:
1. Since there are two ways to go from point D, I went in both directions, so there appear to be 2 answers.
2. Same explanation as in problem 1.
3. I counted the same number of points from both A and G until I came upon one point, and then I looked at the number which the letter was above.
4. since A - C is a segment that there are lots of in this problem, there are multiple answers.
Tell me if I'm wrong :)
