Answer:
I have multiple answers for this.
Verticle Angles: 2 &4, 3&1, 6&8, 7&5
Supplementary Angles: 2&1, 2&3, 3&4, 1&4, 6&7, 7&8, 6&5, 5&8
Explanation:
Verticle angles are aross from one another, not next to each other, while the Supplementary angles ARE next to each other and not across from one another. I hope this helps you :)
