Answers: Choice B, Choice C, Choice D
Basically it's almost everything but choice A
==================================================
Step-by-step explanation:
When intersecting two lines to form an X shape, the vertical angles are the ones that form opposite one another. They do not have to align vertically, meaning they don't have to be stacked on top of one another. They could be side by side.
This applies to the following angle pairs
- 1 and 3
- 2 and 4
- 5 and 7
- 6 and 8
- 9 and 11
- 10 and 12
- 13 and 15
- 14 and 16
The items in bold apply to choices B through D
Side note: Vertical angles are always congruent.
